5/16 x 5/16 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) is used when a precision shoulder needs to locate, guide, space, or support movement in a mechanical assembly. When installed in the proper assembly, the 5/16 x 5/16 shoulder can provide a precision shoulder for bearing contact while the socket head remains serviceable. Typical uses for the 5/16 x 5/16 shoulder include machine guards, inspection fixtures, and guided maintenance components. For the 5/16 x 5/16 size, the material helps reduce corrosion concerns compared with plain steel while keeping a bright appearance on visible assemblies, which can matter to purchasing departments. The 5/16 x 5/16 socket head form also supports compact installation where access for service tools matters. It can help keep OEM assemblies consistent when the 5/16 x 5/16 shoulder is part of the movement or spacing requirement.
