Precision Shoulder Screw - Socket

Precision Shoulder Screws, also known as shoulder bolts, are fasteners with an unthreaded cylindrical section, or shoulder, between threads and screwhead. The shoulder is larger in diameter than the threaded section and provides an axis around which close-fitting moving parts operate. Shoulder screws are available with an undercut shoulder where the diameter of the shoulder can be as small as the minor diameter of the threads. Precision socket shoulder screws are identified by the diameter and the length of the shoulder. Precision shoulder screws can also be produced with a hex socket head. Precision shoulder screws differ from standard shoulder screws in that they have very tight dimensional tolerances. Precision shoulder screws are typically available in stainless steel but can also be made from alloy steel and brass. Please see our listing for Precision Shoulder Screws - Slotted as well.
