1/2 x 2 3/4 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert is commonly specified where a shoulder must guide, locate, or support a moving component instead of acting only as a clamp. Unlike a standard socket head cap screw, the unthreaded shoulder is the working surface for bearing contact, location, or controlled travel. Typical applications include fixture plates, sliding elements, guide rails, and repeatable locating features. The nylon insert is useful in assemblies where a shoulder screw or stripper bolt must stay seated while nearby components move or cycle. Industrial distributors can position this as a shoulder screw and stripper bolt option for tooling, fixture, and maintenance demand. The design is useful when the fastener is part of the positioning system rather than only a threaded clamping point. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.
