1/4 x 3/8 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) supports fixture and automation work where the shoulder must guide a component through repeated movement. At the 1/4 x 3/8 size, the shoulder is intended to control movement while preserving a repeatable spacing point. Common placements for the 1/4 x 3/8 size include pivots, stops, linkage points, and machinery that depends on shoulder contact. When machine builders need the 1/4 x 3/8 size, 18-8 stainless steel provides a clean, corrosion-resistant option for shoulder screw locations in general industrial service. Its 1/4 x 3/8 geometry helps the assembly use the shoulder as the functional surface instead of relying on simple clamping. The 1/4 x 3/8 combination of socket drive access and shoulder geometry helps simplify installation, service, and replacement in compact machinery.
