1/4 x 3/4 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. Unlike a standard socket head cap screw, the unthreaded shoulder is the working surface for bearing contact, location, or controlled travel. Typical applications include assembly equipment, pivoting components, locating nests, and serviceable machine designs. The nylon insert is useful in assemblies where a shoulder screw or stripper bolt must stay seated while nearby components move or cycle. Tool and die shops often evaluate this family when stripper plate travel or fixture alignment depends on a consistent shoulder surface. 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.
