3/4 x 1 1/2 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert helps locate or guide moving parts in equipment where alignment and controlled travel are part of the design. The shoulder screw design separates the functional bearing or locating surface from the threaded retention point. Typical applications include cams, linkages, pivot arms, guide blocks, and machine stops. The nylon insert adds resistance to loosening in vibration-prone or movement-related assemblies without changing the basic shoulder function. 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.
