Gewindestifte

Gewindestifte, also known as setscrews, are headless screws that are threaded internally and used to secure an object within or against another object. They are typically tightened by means of an internal hexagonal socket or a slot. Unlike bolts or cap screws, Gewindestifte do not protrude from the object they are securing. Their primary function is to prevent relative motion between two parts, such as stopping a pulley from rotating on a shaft.

The design of a Gewindestift allows for its entire body to be recessed into a hole or a counterbore in the component it is fastening. This is particularly useful in applications where a smooth exterior surface is required or where space is limited. The tip of the Gewindestift can be designed in various forms, such as flat, cone, cup, or dog point, each suited for different holding requirements. A cup point, for instance, creates a dimple on the mating surface, providing a strong hold.

Gewindestifte are commonly manufactured from steel, stainless steel, or brass, with different material choices offering varying levels of strength and corrosion resistance. They are available in a wide range of metric and imperial thread sizes and lengths to suit diverse applications. Industries that frequently employ Gewindestifte include machinery manufacturing, automotive, electronics, and aerospace, where precise positioning and secure fastening are crucial.
