Furniture self-tapping screw confirmed. Confirmation: sizes, types, purpose. What is confirmation and what is it used for?

Confirmat is one of the varieties of furniture screws; it is also called a screw tie, euroscrew and euroscrew. Elements such as furniture confirmations are in considerable demand due to the incredible precision of their fit and ease of use. To install it, you will need a hex wrench or a drill with a special attachment. Its device allows you to drill the necessary holes directly when assembling the product structure. A special drill for confirmations is available and can be found in construction stores quite problematic.

Confirmats allow you to fasten together several parts made of natural wood. Often used in assembling furniture, as well as construction and carpentry products. Features of these elements:

belongs to the category of hardware high class. Manufactured in a factory;
For its production, exclusively high-quality carbon steel is used. Has an anti-corrosion coating based on zinc, nickel or brass;
complete coincidence of the diameter of the rod and smooth surface. This feature made it possible to fasten the material as efficiently as possible, thanks to tight contact. To level the parts used, you can use a regular mallet;
Furniture confirmations have a large rod and threaded surface, due to which the load on the material being fastened is small. Such designs have excellent resistance to impacts;
have massive threads that protrude significantly above the base of the rod. At the bottom there are serrations and coils;
outwardly resembles a small rod. Its head is slightly flattened, but the bottom is a blunt end.

The advantages of such fittings are as follows:

able to tightly tighten any parts;
quite easy to install;
when using such a fastening, the design will acquire a better level of adhesion;
such parts can be connected to each other;
the use of confirmations will allow the structure to withstand significant loads for a long time. But to attach a bookshelf, it is recommended to use a dowel and confirmation.

There are also disadvantages:

Once the product has been assembled, it will no longer be possible to disassemble it. Such structures will not withstand regular assembly and disassembly;
Such fastenings do not belong to the hidden category, so they require additional masking using plastic plugs, which are selected according to the color of the product.

Dimensions

To make the drilling process as easy as possible, you should use special drills that are produced exclusively for Euroscrews. They consist of a regular drill and cutter and are used to make holes with diameters of 0.7 cm. This size is ideal for both countersinking and a confirmed neck.

The following screws are available:

which have a semicircular head;
their head is secret;
with tetrahedral slot;
with hexagonal slot.

With a semicircular head

With countersunk head

It is very difficult to find such equipment for sale. However, even it has a number of minor drawbacks. To begin with, during prolonged use, wood shavings begin to clog in the space between the skirt and the drill. If you do not carry out timely cleaning, over time the drill will become unusable. The clamping screw should be tightened frequently as vibration will loosen it.

Dimensions may be as follows:

7*70 – the weight of 1,000 products will be 21 kg;
7*60 – the weight of 1,000 products will be 14 kg;
7*50 – the weight of 1,000 products will be 9 kg;
7*40 – the weight of 1,000 products will be 7.2 kg;
6.3*50 – the weight of 1,000 products will be 8.3 kg;
6.3*40 – the weight of 1,000 products will be 7 kg;
5*50 – the weight of 1,000 products will be 5.49 kg;
5*40 – the weight of 1,000 products will be 4.4 kg.

If we are talking about drilling a blind hole at the end of the slab, then it is necessary to maintain strict perpendicularity. This is done so that the drill does not accidentally hit the wall.

The most popular sizes are 7*50. The screw tie is tightened using a hex bit, a special wrench, a screwdriver or a drill. You should not use products that are made for a Phillips screwdriver. This technology will not allow existing parts to be tightly pulled together. Subsequently, such a product will become loose.

Manufacturing materials

Working with this material requires a certain skill. To do this, you need to understand the main features of Euroscrews and be confident in the quality of the material being fastened.

Used for the following materials:

fastening wooden sheets;
laminated chipboard;
Plywood;

It is also convenient to use confirmations because to secure them there is no need to install precise markings. The installation process will not take much time. To do this, you will need several holes (for the unthreaded part and for the threaded part). For example, you can take 6 mm confirmat. In this case, a 6 mm drill should be used for the unthreaded part, and a 4 mm drill for the threaded part. For greater confidence in the strength of the connection, it is recommended to use a dowel. This type of fastening is used for furniture (its manufacture and assembly). When conducting installation work It is recommended to use a hex wrench. Steel is used for the manufacture of confirmations, with zinc used as an additional coating.

Nuances of fasteners

Even despite the ease of use of this type of fasteners, for proper operation they require certain skills regarding working with basic types of materials. To make holes, drills with a diameter of 4 mm to 6 mm are used. Under the head you need to use a stepped cutter, which is attached to the drill. It is recommended to use the latter method, since it allows you to correctly make one hole at a time.

In order to make the correct hole, it is necessary to use tools that can operate at high speeds. When using low speeds, the drill will draw in wood chips, thereby not completely cleaning the hole being prepared. Using a cutter you can achieve the perfect hole.

You should pay attention to the fact that when it is removed, chips may form along the edges, which in our case are not critical, since the wide head of the screw will hide them perfectly. The use of this type of fasteners allows you to achieve maximum efficiency thanks to the highly protruding threads that cut firmly into furniture material. For the first time working with confirmations, everyone necessary actions It's better to do it manually.

Euroscrew installation sequence

Plugs for confirmation

This type of plug allows you to completely cover the caps that remain on the surface of furniture parts. Used to give furniture a finished look or for decorative purposes. It can also be used to hide existing holes, and in case of detection of minor defects on the surface of furniture.

The types of plugs are:

self-adhesive;
plastic.

Color variations of the plugs are selected based on the basic tones of the chipboard. Self-adhesive plugs are more popular than plastic ones. They are completely faceless, but extremely easy to use. Their cost is almost the same. Plastic is used to make plastic plugs. The product has a diameter of 1.2 cm and a round shape. They are attached to a small ledge (hexagon), which leaves a confirmation behind it. Self-adhesive elements are considered more universal and are made of melamine. They also have a round shape. Another advantage of the plugs is their thickness, which does not exceed 0.4 mm and makes them almost invisible against the general background.

Chipboard, from which almost all cabinet furniture is made, is fragile. Everyone knows how inconvenient it is to transport. It must either be disassembled completely, or moved very carefully when assembled, since the screws can simply be torn out. seats even under light loads. This is explained very simply. The screw design itself was impractical. The splines quickly licked off, preventing the assemblers from properly tightening the connection. A hammer came to “help” and was used to finish off the screw, breaking the threaded channel. Modern elements Joint connections, which include furniture confirmats, are free from these disadvantages.

What is confirmation and what is it used for?

Confirmat is the same screw, which has its own design features. The body of the screw is more massive, made of high quality steel with anti-corrosion coating. The grade of material allows the screed to not break during twisting and bending loads. Self-tapping thread with wide pitch. The head has a hidden design, and the screw head is elongated. The slots for the tool come in two versions - for a curved screwdriver and a hex key. There is no usual point at the end, it is blunt. There are modifications of Euroscrews in which the head has a cutting surface.

A single-element screed (confirmat) is suitable for joining wood blanks, boards made from waste wood (OSB, chipboard, as well as fiberboard, MDF), and plywood. In addition to connecting the elements, the Euroscrew performs a frame-forming function, because it replaces the traditional angle, withstanding all bending loads. Furniture confirmations are supplemented with special plastic plugs. They disguise the visible part of the hat to match the color of the furniture.

Confirmat: dimensions

As mentioned above, confirmats come with different types of splines. Euroscrews are coated with galvanization, nickel or brass.

The range of tie sizes is presented below. The first number shows the diameter and the second number shows the length of the screw body. Designations are expressed in millimeters: 5.00 x 40.00; 5.00 x 50.00; 6.30 x 40.00; 6.30 x 50.00; 7.00 x 40.00; 7.00 x 50.00; 7.00 x 60.00; 7.00 x 70.00. The main, widely used size is confirmat 7x50.

What is the advantage of connecting parts using confirmat

The confirmat has different sizes. It's relatively inexpensive fastener, which has a number of advantages:

allows you to quickly and reliably connect parts;
does not require special operating skills or complex auxiliary devices;
delicate to the material - does not destroy it;
able to withstand tearing and bending loads;
cabinet furniture on confirmed mats can be assembled and disassembled without destroying the seats.

Technology of using confirmat

It should be said that the hole sizes for confirmation are different. They must be drilled in three different diameters - for thread, for head and for countersunk. Therefore, there are two technologies for creating holes:

In the first case, you can use a regular drill, but you will have to take three different diameters. First you need to drill the entire length of the tie for the thread, then slightly large diameter under the head and finally under the cap flange. The diameter of each drill, naturally, depends on the size of the specific confirmat. This method is inconvenient and time-consuming, although it may be suitable for small volumes of work.

The second option is more professional and has been adopted by qualified people. There is a special drill for confirmation with a step-type cutter. Such a tool simultaneously drills all the holes and makes a hole for the countersunk hole. Application required electric drill in high speed mode.

Euroscrews connect parts at an angle of 90 degrees. In order to make a joint, it is necessary to fasten the two parts together using the way they should be connected according to the diagram. Then you should drill a hole for the confirm screw through the plane of one part into the end of the other. Next, you need to screw in the tie with a screwdriver. Now the connection is ready.

when working with European screws

Despite the simplicity of fastening, you still need to know a few tricks when working with confirmat. This will help avoid such unpleasant situations when the parts being connected are displaced from the required joint position. Sometimes a defect does not have serious negative consequences, except, of course, for the aesthetic appearance of the product. But it happens that these oversights lead to difficulty in functioning, for example, cracks are rubbed out, cracks appear, some parts do not fit into the openings. That's why:

Having drilled the channel using a confirmat drill, there is no need to rush to immediately screw in the screw completely. At the moment when the head is about to enter the hole, it is necessary to clearly fix the parts in the desired position and, holding them, tighten the tie until the end.

If the slab material is loose, for reliability it is worth treating the screw thread with glue.
When assembling block structures, do not fix them rigidly side walls until the free movement of all boxes has been verified.

Conclusion

For those who just want to learn how to assemble furniture with their own hands, perfect option mastering this matter is to apply confirmation. The dimensions here need to be kept as accurately as possible. In order for the ends of the parts to be connected to be even, it is necessary to have an exclusively right angle with respect to the plane. Then assembling furniture with European screws will simply delight and captivate you.

Hello, friends.

Today we will talk about the most used fasteners for the manufacture of cabinet furniture.

The fastening element, known as confirmat, has gained enormous popularity among furniture makers since the 1990s. Its exact name is a single-element screed.

It is also called Euroscrew, Euroscrew and in common parlance it is called “Eureka”, and the strange name confirmat comes from the name trademark Confirmat, used to produce these products by the German company Häfele.

Features and Benefits

The size range of this fastener is presented in the following ratios of outer thread diameter and screw length (mm): 5x40, 5x50, 6.3x40, 6.3x50, 7x40, 7x50, 7x60, 7x70.

The most popular ones include confirmations with a length of 50 and 70 mm with a thread diameter of 7 mm.

Euroscrews with a regular head require additional countersinking of the hole to place the head flush, but they are also available with a small tooth under the head, which provides the hole with a chamfer of the desired size simply during installation.

If the confirmation is mounted on the front surface of the furniture body, then today there is a wide selection of screw heads available for masking, which can be selected in accordance with the decor of the furniture material.

Nuances of fasteners

Despite the versatility of this fastening element and the ease of working with them, a certain skill is required, mainly associated with knowledge of the characteristics of a particular material to be installed.

Holes for confirmations can be made using drills with a diameter of 4.5-5 mm for the screw shaft, and a hole for the head is made with a special stepped cutter attached to the drill.

The last option is the most convenient, as it allows you to prepare holes in one pass.

To make a high-quality hole, it is better to use a high-speed one. At low speeds, the drill can pull the wood and become clogged with chips that will not be completely removed from the hole.

The cutter makes perfect holes, and when removed, the drill leaves small chips along the edge of the holes, which in this case is not critical, since they will be covered by the screw head.

Euroscrews provide more reliable connections than other types of fasteners due to the wide protruding threads that firmly cut into the material.

Confirmations are installed using a screwdriver or drill with the appropriate bits or hand keys.

For beginners, it is better to install it manually in order to control the process, and in case of excessive resistance of the screw during installation, remove the fastener in time, preventing mechanical damage material.

And that's all.

See you in the next articles.

Furniture screed is used only in furniture production. When making furniture, you should not use traditional fasteners instead of furniture ties, because it has special properties that not only facilitate the assembly of furniture, but also allow you to hide the fasteners. Next, we will consider the most commonly used types of furniture screeds and their features.

Confirmat

The most common type of fastener is confirmat. At the same time the easiest to use. With its help, assembling furniture is easier and faster than using other types of furniture screed. Especially if during assembly you have to drill holes for fasteners yourself. Using a confirmat, two parts are connected at an angle of 90 degrees.

Increase

Fig.1.

In order to tighten the two parts, you need to drill two holes. One in one part, with a diameter equal to the diameter of the confirmator head, the other, at the end of the second part, with a smaller diameter equal to the diameter of the threaded part.

As a rule, drills with a diameter of 6 and 5 mm are used for this, respectively. However, there is a combination drill available for drilling holes at the same time. It is very comfortable. There is no need to constantly rearrange drill bits or use two drills at the same time.

Increase

Fig.2.

Confirmat is a universal fastener, but it has some disadvantages and application features.

Confirmat should be used simultaneously with the use of dowels. A dowel is a wooden rod with a diameter of 6-8 mm and a length of 20-30 mm (in the photo below, next to the confirmation). The dowel acts as a guide and does not allow parts to move during tightening.

Increase

Fig.3.

Despite the fact that furniture assembled using confiramate can be assembled or disassembled, furniture made from laminated chipboard does not tolerate this very well. As a rule, after one disassembly, the furniture screed no longer holds well.

The confirmation should be wrapped carefully. The best option is by hand or with a screwdriver at low speed. Otherwise, the confirmation thread turns into a drill, which breaks the hole.

Increase

Fig.4.

In order to recess the head into the body of the furniture part, you should use a wrench and do it carefully, otherwise there is a possibility of the thread breaking. Sometimes it is necessary to pre-calculate.

Confirmat refers to “visible” fasteners. Those. Unlike other types of fasteners, it remains visible, so it is necessary to use special plugs or stickers to hide the fasteners.

Eccentric coupler

An eccentric coupler is often used in the factory production of furniture. The reason for this is the difficulty of drilling holes. An eccentric coupler consists of two parts: a pin and an eccentric. The pin is installed in one part, and the eccentric in another.

Increase

Fig.7.

The main advantage of this type of fastener is that this fastener is hidden and therefore does not damage appearance furniture. In addition, this type of fastener, unlike confirmat, allows you to repeatedly assemble and disassemble furniture, which is important, for example, when moving. Also, using an eccentric coupler, you can connect parts at different angles.

When making furniture yourself, it is not often used due to the difficulty of drilling holes and the inability to correct the joint during assembly. The main difficulty in drilling holes lies in the hole for the eccentric. This hole is not through and requires the use of a special drill - a Forstner drill.

Fig. 10.

In this case, the sampling depth is about 12 mm, and the thickness of the chipboard is 16 mm. The remaining wall thickness is only 4 mm. There is a risk of drilling more than necessary, thereby damaging the piece of furniture. Therefore, when drilling holes for an eccentric tie, it is necessary to use drilling depth limiters.

This tie is a screw and nut with which two sections of furniture are pulled together, for example, two cabinets. To tie cabinets together, 2 to 4 sectional ties are used. Depending on the thickness of the chipboard, there are intersection screeds of various sizes.

Increase

Fig. 12.

Considering that the intersection screed is used to tie cabinets, and the cabinets, in turn, are made of laminated chipboard with a thickness of 16 mm, an intersection screed with a length of 32 mm is most often used. However, there are ties up to 50 mm long, which are used to tighten parts of greater thickness.

Shelf supports

There are a huge number of types of shelf supports. However, they can be divided into two groups: shelf holders for chipboards and shelf holders for glass. In turn, each of these groups can be divided into two types: shelf holders with and without fixation.

The shelf holder for laminated chipboard consists of 2 parts: a rod and a shelf holder.

Increase

Fig. 14.

The screw is installed in the cabinet wall, and the shelf holder is installed in the body of the shelf. To install the shelf holder, you need to drill holes in the shelf and cabinet wall. For most shelf supports, the hole sizes are standardized; they are shown in the figure below. However, when installing the shelf support, you should carefully read the instructions to avoid errors.

Increase

Fig.15.

It should be noted that shelf holders for chipboard come with or without fixation. The shelf holder with fixation has an eccentric mechanism, thanks to which the shelf will be firmly connected to the cabinet wall. Shelf supports with fixation have one more advantage; shelf supports of this type serve as additional reinforcement of the furniture structure.

Increase

Fig. 16.

Glass shelf holders have more simple design. They are attached only to the cabinet walls using a self-tapping screw.

Increase

Fig. 17.

Shelf holders for glass without fixation are a rod or an angle. Shelf holders with fixation have a special screw with which the glass is firmly fixed and cannot accidentally fall out.

Table top screed

A special type of screed is required to connect two parts of a table top. Used in the manufacture of kitchen furniture.

Fig. 19. Screed for table tops. Provides a reliable connection between two parts of countertops. To increase the accuracy of joining parts, it is advisable to use it together with a dowel. For a standard screed, non-through holes with a diameter of 35 mm and a depth of 19 mm are made in the connected parts of the tabletops. The distance between the holes should be 15 mm less than the length of the tie. The groove width must be at least 7 mm.

To tie two tabletops together, use a pair of ties. To install the tie rods, it is necessary to make recesses for the tie rod stops and a slot for the screw. This can be done in various ways. Most affordable option next. The recess for the stops is made with a Forstner drill of a suitable diameter; the slot for the screw can be made using a jigsaw.

Furniture corner

This type of fastener is used to connect two parts. This is a rather fragile connection method, so it is used to fasten parts that are not expected to be affected by heavy loads. Usually this decorative elements, for example, the base of a wardrobe or mezzanine shelves.

Increase
Fig.21.

Often used plastic corners instead of metal ones. They are no less durable, but have a more attractive appearance and the possibility of hidden fasteners. The furniture corner is attached to two mating parts using two self-tapping screws. Then the lid is snapped on, thus hiding the fasteners.

Fig.22.

The furniture fasteners discussed in the article are the most common and most frequently used, due to the fact that these are the most versatile and easy-to-use types of fasteners. In the vast majority of cases, the types of furniture fasteners described are sufficient to assemble any furniture.

When designing and assembling furniture, confirmat is the main fastening furniture element. It is with its help that the main parts made of chipboard are connected to what we designed on paper.

Eurovint, aka confirmat

There are Euroscrews different types, the most commonly used are 6x50, 7x50, 7x70. Long confirmations are used less frequently, for example, to connect parts made of 32mm chipboard. the most popular standard size is 6x50.

The euroscrews of the part are connected at right angles, that is, in one part a hole is drilled in the plane of the part itself, and in the other (a smaller hole into which the confirmat thread itself is screwed) - at the end of the part. Below are the main parameters of the confirmat itself. Can be selected drill diameters for making holes for fastening euro-coils in both parts to be fastened.

How to mark holes for confirmation?

In general, there are 2 ways of drilling holes for Euro screws (confirmations):

We drill holes separately with different drills of diameters - 6-8 mm and 4.2 or 4.5 mm. But this takes a lot of time and does not always work out accurately and evenly. And there is one more nuance, it is advisable to do it secretly under the screw head, because then it cannot crumble the laminate when twisted chipboard surfaces or protrudes above the surface. Another important point- so that the laminate does not crumble on back side slabs when drilling - it is necessary to lay some kind of unnecessary detail from chipboard or wood.
A special drill for confirmation, which drills both holes and also makes it in secret. In this case, both parts are fastened corner clamps immediately in the position required and immediately after drilling, the confirmat is screwed in.

When connecting parts using a confirmat, there is no need to drag it, otherwise the chipboard may burst. If the parts have moved, you need to unscrew the screw a little, press the part as necessary, and then tighten it again. To do this, it is advisable to drill a hole in the part that is being fastened with a diameter of 8 mm so that there is a slight backlash. You can correct the relative position of the parts with a rubber hammer, but within reason. After tightening the euroscrew/confirmation, its head is closed with a plug (they are multi-colored - to match the color of the corresponding plate).

Video course on the use of confirmations for assembling furniture elements

The article introduces “confirmat” furniture fasteners, and also, using the example of a drawer for a bedside table, describes the technology for assembling furniture using the above-mentioned fasteners.

Confirmat- This is a screw with a blunt end, which is needed to fasten wooden elements together. This screw is screwed in using a cross or hexagonal cutout in the head. More often you can find the second type. Before screwing the confirmat, you need to drill a hole.

The confirmat received its name from the German company Confirmat of the same name, operating in the 1970s. In Russia, this type of fastener, oddly enough, began to be actively used only in the early 1990s.

Confirmat is a representative of a standard furniture connection. Thanks to it, you can easily pull and tightly compress two pieces of wood, which after such a connection will never diverge.

Having studied the information described below, you, by analogy, will be able to assemble furniture in your home with your own hands, ordering only boards cut according to the right sizes and having edges in the right places. Many companies now provide similar services, and self-assembly furniture has long become a favorite “place” where sensible people try to save money.

Technology for assembling furniture “to confirm”.

First of all, let's get acquainted with the tools and accessories that we will need.

Power tools:

1) Drill with drill (photo 2-3) – the diameter of the drill is selected according to the diameter of the confirm thread. Most often it is 5mm.
2) Screwdriver (photo 4) – used for screwing the confirmat into wood. When tightening, significant resistance forces can occur, so make sure that your screwdriver is set to the maximum power setting. To work with the confirmat, a hexagon is inserted into the screwdriver (photo 5).

Hand tools and fixtures:

1) Hex key (photo 6). This key is needed in order to press the confirmat until its cap sinks into the surface of the tree. The convenience of such a key is that it has small sizes and at the same time, to tighten it, it is not necessary to make a full revolution, since the tool has a ratchet, the principle of operation of which is especially well known to motorists.
2) Square with clamps (photo 7). When connecting two wooden elements, the square serves as a lock that prevents the wood from moving apart, making a perfect 90-degree angle.

As already mentioned, we will be assembling a drawer for a nightstand as an example. Such drawers are also popularly called cabinets or bedside tables. Four chipboard boards will be required as prepared raw materials (photo 8). For convenience, all parts of the work will be broken down and described in stages.

Stage 1.

We assemble the boards into the shape of a drawer. Let's look carefully at the edges. Those places where the end of the board connects with the plane of another board do not have a decorative edge. In its place there is an ordinary nondescript saw cut, which is covered either with another board or with a facade. Facade – front side furniture. Having outlined what will be located where, proceed to the direct connection.

Stage 2.

We make one of the 90-degree angles of the drawer for the bedside table. Your task is to make everything as smooth as possible. The junction of two elements should be as smooth as possible. A corner with clamps will help you cope with the task (photo 9). You need to press the sides on it alternately. If you do everything at the same time, you will not achieve evenness! Do not press too hard as this will damage the edges on the wood. While studying corner connection, first set the upper edge and only after fixing it with confirmation, the lower one. Doing everything at the same time, and at the same time smoothly, is a very difficult task!

Stage 3.

Having fixed two wooden element, we begin to drill a hole for the confirmation (photo 10). We do this with a drill. Holding the wooden plank on one side with your hand, use your other hand to bring the drill to the desired point. Your goal is to drill the hole so that it goes through the center of the end of the board (Photo 11). The depth of the hole depends on the length of the confirmat. Pay attention to the photo of the drill (photo 12). It has an extension towards the base. This is necessary in order to obtain a hole into which the thickened part of the confirmat will fit. When drilling, do not immediately make a hole to the entire required depth. At first, it is drilled only until the drill thickens, after which the drill is removed from the wood at speed, and with it the chips. Only after this can you drill the hole to the end. The square with the clamp cannot be removed after drilling!

Stage 4.

On at this stage You will need, directly, the confirmation itself (photo 13). We insert it evenly into the drilled hole (photo 14). Then we tighten it with a screwdriver with an inserted hexagon tip (photo 15). There is no need to tighten the confirmation with a screwdriver until the end (photo 16). You can do this easier and more accurately using a hex wrench (photo 17). We continue to clamp the confirmat with a hexagon until the head of the above “sinks” a little into the wood (photo 18).

Stage 5.

We attach the second side of the drawer for the bedside table. The corner clamp can now be removed. Install by hand correct location the other side and fix in this position (photo 19). With the second hand we drill a hole similar to what we just wrote about. The hole made according to the rules looks like this (photo 20). We twist it into its confirmation and that’s it, one corner out of four is assembled (photo 21-23)!

We repeat the steps until all the corners of your structure are assembled (24-26). Next, the bottom, mechanisms, etc. are screwed to the box. The most important thing is to understand the basic principle, and everything else is related little things.

Using the simple principle described above, you can assemble very complex furniture compositions. By learning this simple technology, you will save a lot of money, since hiring a specialist will be irrelevant for you. Assemble your wardrobes, chests of drawers, bedside tables, show your imagination (photo 27)!

Confirmat, aka euroscrew, aka euroscrew, aka screw tie- this is, simply put, a furniture screw. Loved by furniture makers for its ease of installation and does not require special precision when adding - you only need a drill and a hex key for confirmation.

To install this tie you need two holes: one is drilled at the end the main part, and the other - in the layer part that is attached to the main one. Confirmat is so easy to add that you can even drill holes for it on site during the assembly process of the product. Even a novice furniture maker can handle this.

In order to simplify drilling holes for Euroscrews, a special drill is available. consists of a cutter and a regular drill. The cutter is designed for drilling a hole with a diameter of 7 mm (for the neck of the confirmat) and countersinking (for the head of the confirmat). The drill is inserted into the cutter skirt and clamped with a screw.

Often, such a drill is not so easy to find on sale, especially in small towns. But even if you don't buy it, don't be upset, it has some drawbacks. This is my personal opinion.

The first thing I encountered when working with a confirmation drill was that with a large amount of work, over time, sawdust became clogged between the drill and the cutter skirt. This quickly leads to the drill becoming unusable. Vibration causes the clamping screw to loosen. You have to clamp it more often, so the edges on the key and eventually on the screw itself get licked off.

I don't use a confirmation drill. I use two regular drills ( different sizes under the thread and neck of the screw) and countersink.

Important nuance:

When drilling a blind hole into the end of a slab, it is important to maintain perpendicularity so that the drill does not pierce the wall of the part! I speak from my own experience.

But, I digress a little. An article about confirmation...

The most popular confirmation is 7x50. The screw tie is tightened with a special key by hand or a hex bit using a drill or screwdriver.

Under no circumstances buy confirmations made to fit a Phillips screwdriver! With such a Euroscrew you will not be able to tighten the parts as tightly as possible. This may cause the product to become loose.

Disadvantages of confirmation:

This is not a hidden fastener. You can see the hat. It is usually covered with either a plastic plug or a sticker, matching the color of the chipboard.
furniture that is assembled on confirmations does not withstand repeated assembly and disassembly (no more than three times). This is due to the fact that the confirmat cuts threads in chipboard - relatively soft material. And with frequent disassembly, the thread may break.

Pros of confirmation:

confirmat is easy to install and does not require special equipment or precision when adding (as is the case with minifix). But there is no need to relax. To do quality furniture It is necessary to accurately drill for any fasteners.
The confirmat tightens the parts quite tightly and reliably. “Sits” well in the material.
withstands heavy loads. But in the case of fastening a shelf that is expected to be “loaded” well, confirmat fasteners + dowel are used.
You can correct it with a mallet. For example, align parts at the ends. But in this case, it’s better not to twist the confirmation from there.

In my opinion, the confirmat is convenient, reliable, and quick to use. But if the opportunity arises to use equipment or a device for more complex fasteners, I would choose an eccentric coupler.

P.S. To help people who want to make high-quality furniture with their own hands, I am developing a device made from chipboard for drilling holes for an eccentric and a hinge (). I hope to post it on the website soon.

Confirmat (europrop). Every person has come across furniture made from chipboard more than once, as this is perhaps the widest furniture segment and the most popular due to its affordable price compatible with sufficient quality. In other words, this furniture is called cabinet furniture. The most popular fastener for this furniture is such an element as confirmat. The confirmat was invented by specialists from the German company Häfele in 1973, although in our country this fastener began to be widely used only in the early 90s of the last century.

This furniture tie is a metal rod with a rare external thread, which is used to fasten furniture parts to each other at an angle of 90 degrees. To tighten this type of fastener, the head has a countersunk head with a hex or cross slot. In addition, confirmations can be used for MDF fastenings, timber and various lumber of small thickness.

Installation of confirmat

To install the confirmat, you must first drill holes in the parts to be fastened. For this you can use a regular drill with two drills. For through hole a drill with a diameter of 7 mm is used, and for the internal part a drill with a diameter of 5 mm is used. Using a thinner drill, we drill a hole approximately 10 mm shorter than the threaded connection of the confirmat.

It is very convenient to use a special two-stage drill for this. With its help, you can drill both holes at once. After this, the parts are connected at an angle of 90 degrees and at the same time drilled holes are combined. Next, the confirmat is screwed in. As a result, after completely twisting the confirmat, only the top of the slot remains outside, and threaded connection located inside the chipboard. In this case, the main part of the thread goes into the internal part where we used a 5 mm drill for the hole.

In order to give the furniture a more presentable look, the top of the slot is covered with plastic plugs matching the color of the chipboard.

Advantages and disadvantages of confirmations

The main advantage of confirmats, which allowed them to gain popularity, is ease of installation. Also, this type of fastener does not require great precision. Confirmat has a very simple design and provides a fairly reliable connection of parts. Due to its design, the confirmat works like a self-tapping screw. Thus, when twisting into chipboard, minimal destruction of the material structure occurs.

Flaws are also inherent in confirmats. The first of them is that during installation one of the holes is through and the end of the fastener is visible on the front side of the part. It can be closed with a plug, but not everyone likes it. Another disadvantage of fastening elements is the reduction in the load-bearing capacity of the fastening during the process of repeated disassembly and assembly of furniture, for example when moving.

As you know, the main part of the furniture where these fasteners are used is assembled from chipboard - which in turn is made from sawdust and shavings. If drilled in chipboard hole twist and unscrew the confirmat from it several times, the contacting material is cut by the thread and the connection becomes loose. It is not recommended to assemble more than three times.

Main sizes of confirmations

5*40mm,5*50mm, 6.3*50mm, 7*50mm, 7*60mm,7*70mm.

The most popular size is 7*50 mm with hexagonal slot.

Confirmat is a representative of a standard furniture connection. Thanks to it, you can easily pull and tightly compress two pieces of wood, which after such a connection will never diverge.

Having studied the information described below, you, by analogy, can assemble furniture in your home with your own hands, ordering only boards cut to the required dimensions and having edges in the right places. Many companies now provide similar services, and self-assembly of furniture has long become a favorite “place” where sensible people try to save money.

Technology for assembling furniture “to confirm”.

First of all, let's get acquainted with the tools and accessories that we will need.

Power tools:

Hand tools and fixtures:

1) Hex key (photo 6). This key is needed in order to press the confirmat until its cap sinks into the surface of the tree. The convenience of such a wrench is that it is small in size and it is not necessary to make a full turn to tighten it, since the tool has a ratchet, the principle of operation of which is especially well known to motorists.
2) Square with clamps (photo 7). When connecting two wooden elements, the square serves as a lock that prevents the wood from moving apart, making a perfect 90-degree angle.

Stage 1.

We assemble the boards into the shape of a drawer. Let's look carefully at the edges. Those places where the end of the board connects with the plane of another board do not have a decorative edge. In its place there is an ordinary nondescript saw cut, which is covered either with another board or with a facade. Facade – the front side of the furniture. Having outlined what will be located where, proceed to the direct connection.

Stage 2.

We make one of the 90-degree angles of the drawer for the bedside table. Your task is to make everything as smooth as possible. The junction of two elements should be as smooth as possible. A corner with clamps will help you cope with the task (photo 9). You need to press the sides on it alternately. If you do everything at the same time, you will not achieve evenness! Do not press too hard as this will damage the edges on the wood. When making a corner connection, first set the upper edge and only after fixing it with confirmation, the lower one. Doing everything at the same time, and at the same time smoothly, is a very difficult task!

Stage 3.

Having fixed the two wooden elements, we begin to drill a hole for the confirmation (photo 10). We do this with a drill. Holding the wooden plank on one side with your hand, use your other hand to bring the drill to the desired point. Your goal is to drill the hole so that it goes through the center of the end of the board (Photo 11). The depth of the hole depends on the length of the confirmat. Pay attention to the photo of the drill (photo 12). It has an extension towards the base. This is necessary in order to obtain a hole into which the thickened part of the confirmat will fit. When drilling, do not immediately make a hole to the entire required depth. At first, it is drilled only until the drill thickens, after which the drill is removed from the wood at speed, and with it the chips. Only after this can you drill the hole to the end. The square with the clamp cannot be removed after drilling!

Stage 4.

At this stage, you will need, directly, the confirmation itself (photo 13). We insert it evenly into the drilled hole (photo 14). Then we tighten it with a screwdriver with an inserted hexagon tip (photo 15). There is no need to tighten the confirmation with a screwdriver until the end (photo 16). You can do this easier and more accurately using a hex wrench (photo 17). We continue to clamp the confirmat with a hexagon until the head of the above “sinks” a little into the wood (photo 18).

Stage 5.

We attach the second side of the drawer for the bedside table. The corner clamp can now be removed. We set the correct location of the second side by hand and fix it in this position (photo 19). With the second hand we drill a hole similar to what we just wrote about. The hole made according to the rules looks like this (photo 20). We twist it into its confirmation and that’s it, one corner out of four is assembled (photo 21-23)!
