3/16 x 3 1/4 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) provides a shoulder screw and stripper bolt option for assemblies requiring guided travel or repeatable location. The unthreaded shoulder is the functional feature that separates this product family from simple clamping hardware. The shoulder can provide a bearing surface for sliding or rotating components while the threaded portion secures the fastener. The 3/16 x 3 1/4 shoulder combination supports exact catalog selection for robotics, packaging machinery, inspection fixtures, and serviceable machine components. For engineers, tool and die shops, OEM manufacturers, and maintenance professionals, this alloy steel shoulder screw helps match the bearing surface to the assembly without inventing thread details. Automation systems, tooling plates, machine frames, and engineered fastening locations are common sourcing contexts for this product family.
