1/4 x 5 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 assembly equipment, pivoting components, locating nests, and serviceable machine designs. The nylon insert is useful in assemblies where a shoulder screw or stripper bolt must stay seated while nearby components move or cycle. Engineers can use the shoulder-size pair to match the bearing surface and travel requirement without changing the dimensional convention. The socket head shoulder screw format is well suited to serviceable machinery where access and repeatable location are both important. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.
