M8 x 16 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) is well suited for metric assemblies where the shoulder geometry is part of the motion-control or locating function. The key design value is the shoulder: it provides the functional surface for bearing contact, repeatable location, or controlled travel. Common uses include assembly fixtures, fixture construction, guided-motion assemblies, and machine building; related sourcing may also include international OEM equipment. Purchasing managers benefit from a clear size callout that separates the two shoulder dimensions for RFQ sourcing. 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.
