3/8 x 3 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) gives machine builders a stainless shoulder screw for pivot points, bearing surfaces, guide positions, and spacer locations. At the 3/8 x 3 size, the shoulder is intended to combine fastening with a functional shoulder used for position and motion control. Common placements for the 3/8 x 3 size include die components, moving plates, cams, and guide mechanisms. When purchasing departments need the 3/8 x 3 size, the stainless material supports general-purpose corrosion resistance for fixtures, automation equipment, and OEM machinery exposed to moisture. For OEM work, the 3/8 x 3 shoulder provides a clear locating surface while the socket head remains accessible. It can help keep OEM assemblies consistent when the 3/8 x 3 shoulder is part of the movement or spacing requirement.
