1/2 x 1/2 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) fits applications where the shoulder is used as a functional guide surface rather than a simple fastener shank. For the 1/2 x 1/2 shoulder size, the shoulder can control movement while preserving a repeatable spacing point. In practice, this 1/2 x 1/2 Stripper Bolt is suitable for inspection equipment, packaging machinery, guide rails, and removable machine details. For fixture designers specifying the 1/2 x 1/2 size, 18-8 stainless steel provides a clean, corrosion-resistant option for shoulder screw locations in general industrial service. Its 1/2 x 1/2 geometry helps the assembly use the shoulder as the functional surface instead of relying on simple clamping. This 1/2 x 1/2 design supports tooling and fixture work where simple clamping would not provide the same functional bearing surface.
