1/4 x 5/16 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) is selected for machinery where a precision shoulder provides bearing contact, location, or spacing in a serviceable joint. For the 1/4 x 5/16 shoulder size, the shoulder can help a guided part move predictably against a defined shoulder surface. In practice, this 1/4 x 5/16 Stripper Bolt is suitable for material-handling mechanisms, spacer locations, and serviceable pivot points. For fixture designers specifying the 1/4 x 5/16 size, 18-8 stainless steel is a practical choice where corrosion resistance and a clean finished look matter on exposed or serviced hardware. Specify the 1/4 x 5/16 Socket Head Shoulder Screw when the shoulder function is central to the assembly design. This 1/4 x 5/16 design supports tooling and fixture work where simple clamping would not provide the same functional bearing surface.
