1/4 x 2 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert gives engineers a stripper bolt option for applications where the shoulder geometry is central to movement or location. The shoulder screw design separates the functional bearing or locating surface from the threaded retention point. Typical applications include assembly equipment, pivoting components, locating nests, and serviceable machine designs. The nylon insert supports resistance to loosening while the shoulder continues to provide the bearing, guide, spacer, or locating surface. Tool and die shops often evaluate this family when stripper plate travel or fixture alignment depends on a consistent shoulder surface. 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.
