The RS Pro setscrew is fully threaded and typically fully inserted into a tapped (threaded) hole in the receiving object, requiring no nut for securing. It is primarily used to connect two or more objects in applications such as automotive, machinery, engines, manufacturing, industrial equipment, and white goods. The hexagon head allows for easy tightening and loosening using a socket drive or spanner. Setscrews can be repeatedly removed and reinserted, making them versatile for various tasks.
