M16 x 80 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. This format is different from standard socket head cap screws because the shoulder is intended to carry the locating or motion-control role. Common uses include positioning assemblies, material-handling equipment, locating features, and plant repair programs; related sourcing may also include metric tooling. Machine builders can use this Socket Head Shoulder Screw where internal hex drive access and a functional shoulder are both required. This product family is appropriate where the fastener is part of the positioning system, not just a clamping point. It can also support guide mechanisms, fixture stops, and replacement maintenance where a consistent shoulder surface is part of the design.
