3/4 x 1 1/4 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. Unlike a standard socket head cap screw, the unthreaded shoulder is the working surface for bearing contact, location, or controlled travel. Typical applications include cams, linkages, pivot arms, guide blocks, and machine stops. The insert feature gives buyers a nylon-insert shoulder screw option for applications where retention matters alongside guided movement. Industrial distributors can position this as a shoulder screw and stripper bolt option for tooling, fixture, and maintenance demand. As a stripper bolt, it can support tooling and guided-motion applications where the shoulder is part of the operating interface. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.
