3/8 x 1 1/4 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) fits applications where the shoulder is used as a functional guide surface rather than a simple fastener shank. At the 3/8 x 1 1/4 size, the shoulder is intended to maintain alignment in assemblies that move, index, or return to the same location. Common placements for the 3/8 x 1 1/4 size include inspection equipment, packaging machinery, guide rails, and removable machine details. When industrial distributors need the 3/8 x 1 1/4 size, 18-8 stainless steel offers general-purpose corrosion resistance, a clean appearance, and useful moisture resistance in many industrial environments. Selection should be based on the 3/8 x 1 1/4 shoulder size, material, and machine function required by the assembly. The 3/8 x 1 1/4 precision shoulder is especially useful where pivots, guides, spacers, or locating surfaces must stay consistent through service cycles.
