M6 x 16 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) is commonly specified when a metric assembly needs a controlled bearing surface for pivots, guides, spacers, or locating points. This format is different from standard socket head cap screws because the shoulder is intended to carry the locating or motion-control role. Common uses include international OEM equipment, cams, linkages, and pivoting arms; related sourcing may also include positioning assemblies. Repair technicians may source this product when service work calls for the same metric shoulder pair used in the original assembly. Selection should follow the exact metric shoulder diameter, shoulder length, material, and function required by the assembly. It can also support guide mechanisms, fixture stops, and replacement maintenance where a consistent shoulder surface is part of the design.
