M12 x 80 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) supports engineers designing metric tooling and OEM equipment with precise location, spacing, or guided travel requirements. Unlike a standard socket head cap screw, this shoulder screw uses its unthreaded shoulder as the working surface while the threaded end retains the fastener. Common uses include assembly fixtures, serviceable machine components, guide rails, and assembly-line equipment; related sourcing may also include international OEM equipment. Industrial distributors may stock this style for customers sourcing Alloy Steel shoulder screws for tooling, fixtures, and automation support. 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.
