Shoulder Socket Cap Screws are high-strength fasteners with an Internal Hex or Allen drive style head. The shoulder is a cylindrical unthreaded area before the thread, allowing for rotation of parts and are used in moving parts and other mechanical applications.

The shoulder is the smooth, middle section of the screw that contains the lateral movement of the workpieces. The threaded section has relaxed grooves that have a major diameter slightly smaller than the shoulder diameter. This section is for insertion into a mating thread, be it a nut or tapped hole.
