Set screws are used when one component has to be fixed within another one without any protrusions which could decrease the efficiency of the equipment. For example, fastening a gear and shaft assembly with a regular hex bolt might be inefficient as the hex head might cause inconveniences for the smooth operation of the assembly. In such situations, where protrusions are not desired, a set screw can effectively fasten the components together without interfering with the operations.
Socket Set Screw with a Cup Point are created to DIN 916 standard. They host a hexagonal recess and are driven using a hex wrench or insert bits.
These Set Screws are used in applications to secure objects together, within or against another object.
Cup point set screws feature a hex drive at one end and a cup-shaped indentation at the other. The most commonly used set screw head style, the thin edge of the cup end digs into the contact surface for high holding power. It is useful for fast permanent and semi-permanent placement in applications where some indentation left by the cup end is acceptable.
