1/4 x 2 3/4 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert offers a practical solution when tooling or machine components need both socket-drive retention and a functional shoulder. The shoulder screw design separates the functional bearing or locating surface from the threaded retention point. Typical applications include OEM production equipment, replacement hardware, tooling support, and machine repair. The nylon insert adds resistance to loosening in vibration-prone or movement-related assemblies without changing the basic shoulder function. OEM manufacturers may specify this part where a defined shoulder supports repeatable assembly motion and controlled component location. Selection should follow the required shoulder diameter, shoulder length, material, and assembly function shown for the part. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.
