5/16 x 1/8 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) is commonly used when a compact assembly needs a stainless Stripper Bolt for pivots, guides, stops, or spacers. At the 5/16 x 1/8 size, the shoulder is intended to serve as a locating shoulder in equipment where movement and spacing must remain consistent. Common placements for the 5/16 x 1/8 size include tooling plates, guide blocks, and controlled-travel fixture points. When repair technicians need the 5/16 x 1/8 size, 18-8 stainless steel is often selected for shoulder screw locations where moisture resistance and general-purpose stainless performance are required. The 5/16 x 1/8 size is best matched to assemblies that need a defined shoulder for movement, spacing, or location. The 5/16 x 1/8 precision shoulder is especially useful where pivots, guides, spacers, or locating surfaces must stay consistent through service cycles.
