M20 x 20 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) offers a practical solution when a fastener must also act as a bearing surface, stop, pivot, spacer, or guide. The Stripper Bolt design separates the locating or bearing function from the threaded retention point, which helps maintain alignment in moving assemblies. Common uses include metric production equipment, plant maintenance, tooling support, and guided linear motion; related sourcing may also include assembly equipment. Machine builders can use this Socket Head Shoulder Screw where internal hex drive access and a functional shoulder are both required. 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.
