1/4 x 1 1/4 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. The important engineering feature is the shoulder, which supports positioning and movement while the threaded end retains the fastener. Typical applications include dies, stripper plates, tooling nests, and fixture rebuilds. For maintenance teams, the nylon insert can help address loosening concerns in equipment subject to vibration or repeated motion. Machine builders can use the internal hex drive and shoulder geometry in compact assemblies that still require service access. 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.
