Slotted Head Screws

In this article we would like to go into more detail about slotted head screws made of stainless steel or steel. Slotted head screws are the origin of all screws in the large family. The first screws that were developed had a drive head that was provided with a slot. At that time it was not possible to think of Torx screws or Phillips screws. For this reason the first slotted head screw was provided with a simple but sufficient slot. This slot always runs horizontally over the head surface of the respective screw and flows into the screw head with a certain, defined depth of the slot. This slot is used exclusively as a tool holder for slotted head screwdrivers, which fit exactly into this slot with some play. By using this slotted screwdriver as tool drive, the slotted screw can be tightened or opened again. However, it is important that the screwdriver fits exactly into the slotted head screw without a lot of play and that it is able to rest against the slot flanks over the entire surface. Another important aspect is also that the web of the screwdriver in the slot of the screw reaches right up to the stop, i.e. the end of the slot, as otherwise the slot may "break out". The slotted head screw made of V2A or V4A would then be damaged without exception, which would mean having to replace the screw with a new one. The construction of a slotted head screw corresponds to the basic form of course to that of the other many types of screws, which are provided with the different receptacles. The term "slotted head screw" came about solely because the screw could be named on the basis of the tool holders. A screw always has a larger shaped screw head, which has the corresponding seat (in this case the slot). The shank of the screw that runs away from the screw head ends directly at the screw head. At this shaft, the slotted head screw has the corresponding metric or inch thread rolled in. A connection from a slotted head screw into a component or the corresponding thread is always a frictional connection. This means in plain language that the interlocking of the individual thread flanks into the opposite flank is called frictional connection. The screw with the slot is held in place by the fact that the flanks are firmly anchored together.

Stainless steel slotted head screws or normal steel slotted head screws also belong today in every workshop and in every industrial processing company that wants to permanently secure machine parts or other tool assemblies with fasteners by means of a screw connection. Even today, slotted head screws still play a major role in fasteners, although hexagon socket head screws are probably the most common type of screw, which can be found almost everywhere on machines and components and also in the private sector. Nevertheless, there are still enough companies that depend on slotted head screws, and due to their design, they simply belong to all technical units.

The production of slotted head screws is almost the same as the production of normal screws. However, with a small difference, which we would like to explain to you here in this article. In order to be able to use slotted head screws, these must of course first be manufactured. In order to realize this production, screw machines must be provided to enable a cheap production of slotted head screws. Only by these automats it is possible to enable a cost efficient production in your favour. The automatic screw machine is a CNC machine which has to be prepared for the respective screw by setting up the machine for the respective screw, so that the slotted head screw production can begin. This machine consists of a chuck which feeds the endless wire into the machine to feed it into the production. Outside there is always a drum holder where the raw wire of stainless steel or steel is fed into the machine. Only with the ebndos wire, an economic production is possible, because the machine can produce the slotted head screws almost unmanned. Once the wire has arrived in the chuck, the length of the wire is first cut to length and in a further step the head of the slotted head screw is pre-stressed. A conical upsetting tool is used, which is pressed under high pressure against the shaft of the slotted head screw. In the further connection process, the final screw head is pressed against the slotted head screw by means of a further pressing device. Once this section is also completed, the slot is inserted into the screw head. The screw head of the screw is guided past a side milling cutter and the slot is milled in. Now only the thread on the slotted head screw is missing. This is now attached by rolling it in. The screw is moved between two thread plates and the thread is rolled in by applying high pressure. Once this section of the stainless steel slotted head screw is also completed, the screws are only cleaned of oil or electropolished. Afterwards the slotted head screw can be stored in our warehouse to be sold to you.
