1/2 x 4 1/4 Alloy Steel Shoulder Screw with Nylon Insert

1/2 x 4 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 industrial machinery, maintenance departments, equipment builders, and distributor sourcing. A nylon insert helps add loosening resistance where repeated motion, equipment vibration, or service conditions can work against threaded retention. Engineers can use the shoulder-size pair to match the bearing surface and travel requirement without changing the dimensional convention. 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.
