Socket Set Screws

Sesco Industries is a trusted supplier of aerospace parts for businesses around the country. This includes a wide selection of socket set screws. A socket set screw is a type of screw that is normally used to secure an object within or against another object. Their most common applications are for securing a pulley or gear to a shaft. This sort of screw is usually headless, which means that the screw is fully threaded and has no head projecting past the diameter of the screw thread.

Socket Set Screw Features

If a socket set screw has a head, the thread will extend all the way to the head. A blind set screw is almost always driven with an internal-wrenching drive, such as a hex socket (Allen), star (Torx), square socket (Robertson), or slot. The set screw passes through a threaded hole in the outer object and is tightened against the inner object to prevent it from moving relative to the outer object.

An example application is when a socket set screw is screwed into a pulley hub so that its end-point bears firmly against the shaft. The fastening action is by friction between the screw and the shaft, often with some amount of elastic or plastic deformation of one or both.
