Socket shoulder screws are specialized fasteners designed for applications requiring precise shoulder diameter tolerances and smooth rotating surfaces. These 3/8" shoulder diameter screws feature 5/16-18 coarse threads and a 3/4" length, making them ideal for pivot points, linkages, and bearing applications. Manufactured from stainless steel A2 (18-8), these shoulder screws offer excellent corrosion resistance and durability for both indoor and outdoor use. The socket head design allows for high-torque installation using a hex key while maintaining a low profile. This 2-pack provides quality fastening solutions for machinery, automotive assemblies, and mechanical projects where rotational movement or precise spacing is required. The coarse thread pattern ensures secure fastening in a variety of materials.
