M8 x 40 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) provides a defined shoulder for equipment designs that require repeatable alignment and controlled movement. 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, tooling plates, pivot points, and controlled movement in production cells; related sourcing may also include machine tools. Purchasing managers benefit from a clear size callout that separates the two shoulder dimensions for RFQ sourcing. The design is useful for sliding plates, rotating links, locating nests, and spacer positions where repeatable movement matters. It can also support guide mechanisms, fixture stops, and replacement maintenance where a consistent shoulder surface is part of the design.
