3/4 x 2 3/4 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert offers a practical solution when tooling or machine components need both socket-drive retention and a functional shoulder. The shoulder screw design separates the functional bearing or locating surface from the threaded retention point. Typical applications include cams, linkages, pivot arms, guide blocks, and machine stops. 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. This product family helps support controlled movement in fixtures, guides, pivots, and stops. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.
