5/16 x 3 1/2 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert is frequently selected where dies, fixtures, cams, or linkages require a shoulder surface for repeatable motion. The socket head allows internal hex drive access, while the shoulder provides the surface used by the assembly. Typical applications include conveyor equipment, assembly fixtures, spacer locations, and controlled-travel mechanisms. For maintenance teams, the nylon insert can help address loosening concerns in equipment subject to vibration or repeated motion. OEM manufacturers may specify this part where a defined shoulder supports repeatable assembly motion and controlled component location. Alloy steel construction supports industrial fastening applications where the shoulder performs the working role in the assembly. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.
