Square washers are not round but square. Such square washers are mainly used in timber construction to provide the screw head with a large bearing surface. Especially with soft material such as wood, square washers are ideal for use.
This article will deal with metal square washers, which are mainly used for wooden constructions. We would also like to give you details about the exact application and why they should be used for wood, as well as the production of steel or stainless steel square washers. Furthermore and finally, it is also important for us to give you an understanding of how square washers for wooden constructions can be produced on machines in production and which possibilities are possible. Let us come to the first point regarding square washers, which illuminates the application and the "why" in more detail. It must be said that normal discs can of course also do this? Or. This question is essential, because these discs also resemble square washers the most. But there are serious differences between a normal washer or a K-washer and a square washers! Now the first thing to consider is what tasks such square washers have to perform within wooden constructions. The most important point is always that the screws used are screwed through the wood and must be tightened very firmly. This is generally not the problem, but the problem is when the surface pressure at the nut head or screw head becomes so extremely high that these points can be pressed into the wood. This reduces the screw load capacity and safety if the wood can give way at the hole. Normal welds are firstly much smaller than square washers and secondly also much thinner. Of course, one could now say that K-discs are larger in diameter and perform the same tasks as square washers! No, this is not the case, because, as already mentioned, the thickness also plays a decisive role. If the material is too thin, the disc will bend when tightened and will also press itself into the wood. Especially with the square washers, the surface pressure is chosen so that it decreases with size, which is the case with the square washers. The other advantage that these discs cannot be pressed into the wood is the extreme thickness of the material and the material itself, which we will come to in the following. Square discs can be used as steel square washers or stainless steel square discs. In the case of stainless steel square disks, the alloys differ, if we speak of V2A or V4A. Basically, V2A square disks are completely sufficient for use in wooden constructions. However, if the constructions are to be located near salt water or sea water or in the immediate vicinity of a chemical, such as acids or alkalis, we always recommend the use of V4A square discs. Only these alloys are permanently protected when it comes to freedom from corrosion and permanent weathering-free condition.
Our stock program of square washers - buy online in our Online Shop
Over the last 40 years, the demand for square washers has continued to shift upwards. This is no wonder, since the verses wooden constructions, which have become more and more stable and of high quality, must of course be supplied and screwed together with the appropriate connecting elements. Of course, the square washers metal washers play an increasingly important role in this process. Such square washers usually always have a square shape and a through hole. Of course, there are also square washers that can have a threaded hole, but these washers must have an even thicker material thickness so that the threads really stick in the material and do not tear out under a high load! However, we would like to concentrate on the square washers that have a through hole.

The production of square washers
Now you could already take some information about the square washers with you and many craftsmen and carpenters work daily with square washers for wooden constructions to mount wooden buildings safely, but unfortunately many do not really know anything about the production of square washers. With this article we would like to shed some light on the dark and tell you how a production of these so sought-after discs can be done. In order to be able to assemble and install all of these square washers, they must first be produced on forming machines. Today's so-called CNC forming machines or steel strip processing machines are used for this. These machines are heavy-duty, because they also have to apply great forces to produce square washers and all other materials. In this case, the inner area always consists of the machining station on which the manufacturing processes take place. On the outside there is either a steel strip loader, which can store 6 meters of bars or, for thinner material, a drum on which the steel strip is wound in the desired steel or stainless steel quality. This enables a low-cost and fast, economical production, which can be implemented by this "endless production". When the CNC program is loaded into the machine and the steel strip is inserted, the production of the square washers with the bore can already begin. The strip is then inserted into the machine and the first step is to pre-drill the middle hole in the square washers. Afterwards the boring to the desired diameter takes place. When all these manufacturing processes are completed, the last operation is the cutting of the strip steel by means of a metal circular saw. This results in an almost burr-free cut and the square washers do not need to be reworked. A great advantage during production! All these steel square washers now fall into an attached collecting container and then only need to be washed so that all oil residue disappears and can then be stored in our warehouse as packages of square washers. Now the discs are waiting for your orders and can be comissioned to be shipped to you.
