A shoulder screw, or shoulder bolt, features a precision-machined shoulder for accurate spacing. As trusted shoulder bolt manufacturers, we offer 10-32 shoulder screws, 5/16 shoulder screws, and variants like socket head shoulder screws and hex head shoulder bolts.

Our shoulder screws combine a cylindrical shoulder (for alignment) with threaded ends. Socket head shoulder bolts and hexagon socket head shoulder screws ensure easy installation. Hex shoulder bolts and hex head shoulder screws suit high-torque needs, while 10-32 and 5/16 sizes cater to diverse industrial demands.
