Flat round head screws are also part of the big family and today it is hard to imagine industry and private life without them. That sounds a bit confusing at first, but if we explain something about the stainless steel flat-round head screws or about the steel flat-round head screws in more detail in this article, you will understand what we mean when we want to mark this type of screw as very useful. Have you ever thought about how a normal screw can be screwed into a wooden beam, for example, in such a way that it cannot be opened from the head side? What we mean is that this round head screw is not only a round head screw, but can also act as a safety screw at the same time? This safety function is not provided by a commercially available cylinder head screw or a cross-slotted head screw. However, in many situations, such as when installing or building wooden doors for outdoor use, it is particularly important to ensure that the safety function is guaranteed in such a way that hinges are screwed to doors in such a way that opening the screws from the outside is not possible under any circumstances and must be effectively prevented. All other screws cannot fulfil this function, except the flat round head screws with a square on the screw head. Whereby we would be already with the correct topic, unzwar, with the structure of such important construction units, like the flat round head screws from steel, and/or from high-grade steel (V2A and/or V4A). These screws also have a screw head that ends directly at the shaft of the screw. This shank is a compound with the screw head and made of one piece. As the name suggests, the head of the flat round head screw is very flat and round. One could also say that it is a semicircular head. The special thing about this screw is that the square is attached to the head and placed between the head and the threaded shaft. This square is enormously important, if a special function is attributed to it. This square is inserted into the through hole when a flat round head screw is mounted and the four corners of the flat round head screw dig directly into the round hole so that the screw is automatically secured against twisting when screwed in. The flat round shape of the screw alone does not make it possible to use a pair of pliers to attach and unscrew the screw, but it is even more important that the square head can no longer be turned in the drill hole in parallel. This is a double safety function of every single flat round head screw. These special screws are mainly used in joineries that have to connect a lot of steel parts, such as hinges, with wood through the flat round head screws. But also in private areas such screws can be found more and more frequently.

As we have just been able to explain to you in more detail in the previous article, flat round head screws are now indispensable in manufacturing companies. This special safety screw has become fully established in industrial production and in the private sector. As already mentioned, the reason is very simple. A perfect screw to make attacking with tools absolutely difficult and at the same time to completely prevent twisting. These two serious advantages alone make these flat round head screws so popular. Also the material stainless steel, which is resistant against corrosion and with V4A even resistant against salt water, makes these screws so special. We did not include these screws in our product range as dealers until our long-standing customers had contacted us in different ways by telephone and e-mail to find out whether we could also include flat round stainless steel screws in our product range.

The production of flat round head screws
So that a flat round head screw can also be used and installed in a factory, it is of course particularly important to learn a lot about how these screws are manufactured. In this article we have decided to explain a few things about the production of flat round head screws. In order to produce such screws, special CNC automatic screw machines are required, which are able to produce the correct flat round screws quickly, qualitatively and cost-effectively. Such highly complex machines always have a so-called chuck integrated, in which the screws can be manufactured and pressed. On the outside, there is always a supply of raw wire made of steel or stainless steel, which functions as an "endless wire" and thus moves the machine into the bearings to produce even in night shift mode. This saves further costs and thus achieves a market economy price. The wire is now fed into the machine from the drum through the chuck. Now comes a knife which cuts the wire to the desired length and with a pre-pressing device the head is now upset against the shaft. This creates the collar and at the same time the square under the head. In the last upsetting process, the half-round head is now pressed against the stainless steel flat round head screw. The raw body is now finished. What is still missing is the thread on the shaft of the screw. This is produced by two separate screw thread plates. The shaft of the flat round head screw is rolled back and forth between the two threaded plates with high pressure, so that the thread can be transferred to the shaft of the screw. This thread is called a roll thread. Now the screw is almost finished and must be freed only from the oil remainders of the manufacturing by a washing process. Once this last step in the manufacturing process has been completed, the finished flat round head screw according to DIN can be stored in our warehouse and, if purchased by you, dispatched quickly.
