M16 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 packaging machinery, production fixtures, stop blocks, and pivoting machine elements; related sourcing may also include metric production equipment. OEM manufacturers can specify the same shoulder-size pair when replacement hardware must match an existing metric design. Selection should follow the exact metric shoulder diameter, shoulder length, material, and function required by the assembly. The internal hex drive helps keep installation practical in compact assemblies and serviceable equipment layouts. As a Socket Head Shoulder Screw and Stripper Bolt, it supports machine-design and tooling environments where a defined shoulder is part of the assembly.
