M6 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 industrial robotics, mold components, stops, and controlled-travel mechanisms; related sourcing may also include machine tools. OEM manufacturers can specify the same shoulder-size pair when replacement hardware must match an existing metric design. Alloy Steel construction supports high-strength fastening in precision industrial applications where the shoulder performs the working function. It can also support guide mechanisms, fixture stops, and replacement maintenance where a consistent shoulder surface is part of the design.
