1/4 x 1 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 important engineering feature is the shoulder, which supports positioning and movement while the threaded end retains the fastener. Typical applications include OEM production equipment, replacement hardware, tooling support, and machine repair. The nylon insert supports resistance to loosening while the shoulder continues to provide the bearing, guide, spacer, or locating surface. Purchasing managers get a clear shoulder-size callout for RFQ sourcing and replacement work. 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.
