Shoulder screws, or shoulder bolts, are machine screws that have an unthreaded shoulder under the head that is larger in diameter than the threads. It is this enlarged shoulder that determines the nominal size of the screw.
The shoulder screw is a cylindrical unthreaded area before the thread, allowing for rotation of parts and are used in moving parts and other mechanical applications.
