An Allen wrench is a special screwdriver, which allows a special type of screw to be tightened or loosened. Allen is the abbreviation for hexagon socket fixing screws and these allen wrenches have been on the market since 1936 and they can be used for many different areas. They are used in the furniture industry, in mechanical engineering as well as in aircraft and vehicle construction. The hexagon socket head screws can be the hexagon, which was sunk into the screw head. The construction method allows ten-times the torque to be applied to the regular cross or slotted screw to tighten an Allen screw. The consequence is then the increased stability of the screw connection. Finally, if Allen screws are used, then no one comes here with the normal screwdriver on. It is then always necessary that the appropriate Allen key is used. There are the special screwdrivers in different sizes and they belong to every tool trolley, all tool cases and for all mechanics to the basic equipment. In other countries, the Allen key is also called Allen Key, and every DIY enthusiast around the globe is a basic tool. It is an ingenious invention, which was probably invented in 1911. The Allen key was patented for the first time in 1936 by the German company Bauer and Schaurte. The hexagonal head is the main feature of the screwdriver and here hexagon socket screws are introduced. A particularly high surface pressure is due to the small contact surface.

No problem is the renewed tightening or later loosening of the screws, because optimally the formation of the hexagon is maintained. In SW, the size is specified by the Allen key, where SW stands for the key width. In millimeters the key width is numbered. Especially with the mechanics, however, the unit inch is often used. One inch equals 25.4 millimeters, if the conversion in millimeters is decisive. If the hex wrench offers a ball head, then it can be more easily inserted into the hexagon socket of the screw.
