3/8 x 5 1/2 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert is commonly specified where a shoulder must guide, locate, or support a moving component instead of acting only as a clamp. This stripper bolt format is chosen when a mating part must ride, pivot, stop, or space against the shoulder. Typical applications include conveyor equipment, assembly fixtures, spacer locations, and controlled-travel mechanisms. 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. The socket head shoulder screw format is well suited to serviceable machinery where access and repeatable location are both important. It is appropriate for buyers comparing shoulder screws by exact shoulder diameter, shoulder length, material, and insert feature.
