M16 x 90 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) is designed for assemblies where the shoulder must locate, guide, or support a moving component rather than simply clamp parts together. The internal hex drive supports installation access, while the Alloy Steel body serves applications that call for high-strength fastening. Common uses include indexing equipment, serviceable machine components, guide rails, and assembly-line equipment; related sourcing may also include Asian-built equipment. 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.
