1/2 x 7/8 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) helps solve motion-control and location challenges where the shoulder is the working surface of the fastener. The 1/2 x 7/8 shoulder gives the mating part a surface that can serve as a locating shoulder in equipment where movement and spacing must remain consistent. The 1/2 x 7/8 Socket Head Shoulder Screw can support cleanroom-adjacent equipment, service fixtures, alignment stops, and guided machine details. With the 1/2 x 7/8 shoulder, industrial distributors can use a fastener where 18-8 stainless steel is often selected for shoulder screw locations where moisture resistance and general-purpose stainless performance are required. The 1/2 x 7/8 size is best matched to assemblies that need a defined shoulder for movement, spacing, or location. The 1/2 x 7/8 precision shoulder is especially useful where pivots, guides, spacers, or locating surfaces must stay consistent through service cycles.
