Socket Set Screw

Nationwide Military Parts Distributor

Sesco Industries is a trusted socket set screw supplier. We distribute aerospace parts for businesses around the country. This screw is used for fastening and features a headless design. They are normally used to secure an object within or against another object, but there is no head projecting past the end of the screw thread. These set screws are threaded with a wrenching tool and have a range of point styles.

Their most common applications are for securing a pulley or gear to a shaft. By being headless in design, the screw is fully threaded. This means it has no head projecting past the diameter of the screw thread. We are experts in the world of aerospace parts. Please see our aerospace parts division at Famsales.

Socket Set Screw Features

How does a socket set screw work exactly? Well, this is a screw that has a head. Then, 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 it 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. The durability of the socket set screw makes it great for many military applications and tasks.
