5/16 x 4 3/4 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 dies, stripper plates, tooling nests, and fixture rebuilds. The insert feature gives buyers a nylon-insert shoulder screw option for applications where retention matters alongside guided movement. Machine builders can use the internal hex drive and shoulder geometry in compact assemblies that still require service access. 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.
