5/8 x 5/16 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) helps solve motion-control and location challenges where the shoulder is the working surface of the fastener. In a 5/8 x 5/16 shoulder application, the working surface can combine fastening with a functional shoulder used for position and motion control. Equipment builders may use the 5/8 x 5/16 size in cleanroom-adjacent equipment, service fixtures, alignment stops, and guided machine details. The 5/8 x 5/16 product also gives fixture designers a material choice where the stainless material supports general-purpose corrosion resistance for fixtures, automation equipment, and OEM machinery exposed to moisture. For OEM work, the 5/8 x 5/16 shoulder provides a clear locating surface while the socket head remains accessible. This 5/8 x 5/16 design supports tooling and fixture work where simple clamping would not provide the same functional bearing surface.
