1/4 x 2 1/4 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert is designed for assemblies requiring a shoulder screw that can fasten while also serving as a guide, pivot, or spacer. This stripper bolt format is chosen when a mating part must ride, pivot, stop, or space against the shoulder. Typical applications include automation equipment, indexing stations, positioning assemblies, and OEM machinery. The nylon insert supports resistance to loosening while the shoulder continues to provide the bearing, guide, spacer, or locating surface. Industrial distributors can position this as a shoulder screw and stripper bolt option for tooling, fixture, and maintenance demand. As a stripper bolt, it can support tooling and guided-motion applications where the shoulder is part of the operating interface. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.
