5/8 x 4 1/2 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 material-handling systems, transfer equipment, moving plates, and plant maintenance work. For maintenance teams, the nylon insert can help address loosening concerns in equipment subject to vibration or repeated motion. Purchasing managers get a clear shoulder-size callout for RFQ sourcing and replacement work. Alloy steel construction supports industrial fastening applications where the shoulder performs the working role in the assembly. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.
