1/4 x 1 1/2 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert supports assemblies that need a bearing surface, pivot point, spacer, stop, or locating feature in one fastener. The important engineering feature is the shoulder, which supports positioning and movement while the threaded end retains the fastener. Typical applications include material-handling systems, transfer equipment, moving plates, and plant maintenance work. The nylon insert supports resistance to loosening while the shoulder continues to provide the bearing, guide, spacer, or locating surface. Maintenance professionals may use this style when worn guide, stop, spacer, or pivot hardware needs a direct shoulder-size replacement. 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.
