Knurled Cup Point Socket Set Screws

Socket Set Screws are headless screws, fully threaded from end to end.  They contain a hex (socket) drive on one end and a specific type of point on the other.  Socket Set Screws are found in many assemblies containing rotating features such as wheels, collars, gears or pulleys, where these components need to be locked onto a shaft. Socket Set Screws provide that locking mechanism.  They work by exerting compressional force through the screw point to prevent movement between the object and the shaft.  They are available in a wide range of diameters, lengths and materials, as well as point styles.  The application itself typically determines the most appropriate point style.  Considerations in point selection may include materials involved, the relative hardness of components, the frequency of adjustment or disassembly, along with many other factors.
