M16 x 120 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. Engineers choose this product family when the shoulder must guide, pivot, space, or stop a component with more control than ordinary clamping hardware. Common uses include machine tools, material-handling equipment, locating features, and plant repair programs; related sourcing may also include assembly fixtures. 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.
