5/16 x 3 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) is specified for assemblies that need a precision shoulder to act as a bearing surface, pivot, guide, spacer, or stop. When installed in the proper assembly, the 5/16 x 3 shoulder can maintain alignment in assemblies that move, index, or return to the same location. Typical uses for the 5/16 x 3 shoulder include OEM builds, repair work, guide assemblies, and equipment that needs repeatable location. For the 5/16 x 3 size, 18-8 stainless steel offers general-purpose corrosion resistance, a clean appearance, and useful moisture resistance in many industrial environments, which can matter to fixture designers. Selection should be based on the 5/16 x 3 shoulder size, material, and machine function required by the assembly. This 5/16 x 3 design supports tooling and fixture work where simple clamping would not provide the same functional bearing surface.
