Particleboard, from which almost all cabinet furniture is made, is fragile. Everyone knows how inconvenient it is to transport Soviet furniture. It must either be completely disassembled or moved very carefully in the assembled state, since the screws can simply be pulled out of their seats even under light loads. This is explained very simply. The design of the screw itself was impractical. The slots quickly licked off, preventing the assemblers from tightening the connection with high quality. A hammer came to the "help", with which they finished off the screw, breaking the channel, cut into threads. Modern joining elements, which include furniture confirms, are devoid of these shortcomings.
What is a confirmation, what does it serve for
Confirmat is the same screw that has its own design features. The body of the screw is more massive, made of high quality steel with anti-corrosion coating. The brand of material allows the screed not to break during twisting and under bending loads. Self-tapping thread with a wide pitch. The cap has a hidden design, and the screw head is elongated. The slots for the tool go totwo versions - for a curly screwdriver and a hex key. There is no usual sharpening at the end, it is blunt. There are modifications of Euroscrews, in which the cap has a cutting surface.
Single-element tie (confirmat) is suitable for joining wood blanks, boards made on the basis of wood waste (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 corner, withstanding all bending loads. Furniture confirmations are supplemented with special plastic plugs. They mask the visible part of the hat to match the color of the furniture.
Confirm: sizes
As mentioned above, confirmations come with different types of slots. Euro screws are coated with galvanization, nickel or brass.
The size range of ties is shown below. The first digit indicates the diameter of the threaded connection, and the second indicates 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 joining parts using confirmate
Confirmat sizes are different. This is a relatively inexpensive fastener that has several advantages:
- allows you to quickly and reliably connect parts;
- does not require special skills in work and complex auxiliarydevices;
- delicate to the material - does not destroy it;
- capable of withstanding pull-off and bending loads;
- cabinet furniture at confirmations can be assembled and disassembled without destroying seats.
Technology for the application of confirmation
It should be said that under the confirmation the hole sizes are different. They must be drilled with three different diameters - under the thread, under the head and under the sweat. Therefore, there are two technologies for creating holes:
In the first case, you can use a regular drill, but you have to take three different diameters. First you need to drill the entire length of the tie for the thread, then a slightly larger diameter for the head and, finally, for the flange of the cap. The diameter of each drill, of course, depends on the size of a particular confirmation. This method is inconvenient and time consuming, although it may be suitable for small amounts of work
The second option is more professional and adopted by qualified furniture assemblers. There is a special drill for confirmation with a step-type cutter. Such a tool simultaneously drills all the holes and makes a selection for the sweat. Requires the use of an 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 with an angle clamp in the way they should be connected according to the diagram. Then you should drill a hole for the confirmation screw through the plane of one part to the endanother. Next, you need to screw the screed with a screwdriver. Here is the connection and you're done.
How to avoid mistakes when working with euro screws
Despite the simplicity of fasteners, you still need to know a few tricks in working with a confirmation. This will help to avoid such unpleasant situations when the connected parts are displaced from the desired joint position. Sometimes a defect does not have serious negative consequences, except, of course, the aesthetic appearance of the product. But it happens that these oversights lead to the complexity of functioning, for example, drawers are overwritten, cracks appear, some details do not enter the openings. Therefore:
Having drilled a channel using a confirmatory drill, there is no need to rush to immediately screw the screw in 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 to the end
- If the plate material is loose, for reliability it is worth treating the screw thread with glue.
- When assembling block structures, do not rigidly fix the side walls until the free movement of all drawers has been checked.
Conclusion
For those who only want to learn how to assemble furniture with their own hands, the ideal option for mastering this business is to apply confirmation. The dimensions here must be maintained as accurately as possible. In order for the ends of the parts to be joined to be even, it is necessary to have an exclusively right angle with respect to the plane. Then assembling furniture with euro screws will simply delight and captivate.
