1/2 x 1 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert gives engineers a stripper bolt option for applications where the shoulder geometry is central to movement or location. The shoulder screw design separates the functional bearing or locating surface from the threaded retention point. Typical applications include conveyor equipment, assembly fixtures, spacer locations, and controlled-travel mechanisms. The nylon insert adds resistance to loosening in vibration-prone or movement-related assemblies without changing the basic shoulder function. 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. It is appropriate for buyers comparing shoulder screws by exact shoulder diameter, shoulder length, material, and insert feature.
