Knurled Screws

Stainless steel knurled screws are also a special type of screws that were created for very special applications. Especially the material stainless steel, V2A or V4A, for example, is used again and again in industrial production, in the food industry and everywhere where it is important that no corrosion or rust may set in. Stainless steel knurled thumb screws are completely different from the standardized normal DIN screws. Of course the knurled screw, like the other screws, has a screw head, which naturally has a shank on the underside. This shank is equipped with a thread to screw the knurled screw also into a threaded hole or a nut. The head of the knurled screw is equipped with a very wide collar, which allows to screw the knurled screw into a thread without any tools and thus to connect two or more components with each other. The wide collar of the screw is provided with a strong knurl, so that you can create enough grip to tighten or loosen the knurled screw with only thumb and index fingers in threaded holes. There are knurled screws that have no slot in the head to allow for a possible fastening with a screwdriver. The same screw is also available without a slot in the upper edge of the screw head. So there is also the possibility to use knurled screws with an oversized head and in the inside of the head of a hollow turned material, so that the screw with the knurl becomes very light of weight. These knurled screws made of V2A or V4A or also of treated steel can be found today in industrial production in many technical devices or plants. Especially in the construction of jigs and fixtures, where closures or other machine parts have to be removed or moved quickly and without complications, you will find knurled screws in abundance. Especially also protective covers of machines are often equipped with screws, which make it possible to loosen and tighten the connection to another machine part without any tools. As you can see, knurled screws offer very good possibilities to adjust fixtures without tools, just like wing screws.

As we were able to show you in the previous article, knurled screws are indispensable connecting elements today and are used thousands of times a day in Europe. In addition to the standard screws with tool holders in or on the head, knurled screws are true specialists when it comes to achieving relatively high torques, loosening the screws or even tightening them and all this without any tools. Especially in fixture construction, screws with a stainless steel knurl are indispensable. This type of screw was added to our product range relatively late, as we were not aware at this early stage that these screws also have a very special significance for our customers from industry and private households. After we had received some mails and telephone calls and we were asked about the possible delivery of stainless steel knurled screws, it became clear to us that we also wanted to include these screws in our stock program in the near future, so that our customers can benefit from them. So we searched for a supplier who can supply us with larger quantities of knurled screws in a timely manner.

In order to be able to use your knurled screws in private homes or industrial production, it is of course most important that these products are manufactured first. As the production of knurled screws differs slightly from standard commercial screws, we would like to explain the production process in more detail, so that you can also judge the production of knurled screws well. For the production of such screws basically two machine types are used. On the one hand it is possible to produce the knurled screws on standard CNC lathes or on CNC screw machines. With these screws it does not really matter on which machine you have the parts turned. Since knurled screws are not a real mass product, the thread of these screws is actually always cut instead of rolled. In order to be able to produce a knurled screw on a CNC lathe, first of all the raw material is placed in the loader behind the machine. Once the machine is prepared for the production of the knurled screws, the raw steel material can be inserted into the chuck of the machine. Once this manufacturing process is completed, the first step is to screw the contour on the raw material. The next step is to cut the metric thread on the knurled screw. Now the knurling can be attached to the screw as the next step. For this purpose, the knurling tool is moved against the raw material with very high pressure. Now the knurling is applied to the knurled screw. When this section is completed, the screw can be cut off. Now the almost finished knurled screw is ready and only needs to be washed to remove the last oil residues. If this stage of the production is also completed, the screw can be stored in our warehouse to be delivered to you with an online order.
