5/16 x 2 1/2 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) fits applications where the shoulder is used as a functional guide surface rather than a simple fastener shank. In a 5/16 x 2 1/2 shoulder application, the working surface can keep sliding or rotating components aligned around a defined contact area. Equipment builders may use the 5/16 x 2 1/2 size in inspection equipment, packaging machinery, guide rails, and removable machine details. The 5/16 x 2 1/2 product also gives engineers a material choice where the corrosion-resistant stainless construction suits plant maintenance, fixture work, and equipment that may be handled or cleaned regularly. The 5/16 x 2 1/2 configuration can help maintenance teams keep guided components aligned after service or replacement. It can help keep OEM assemblies consistent when the 5/16 x 2 1/2 shoulder is part of the movement or spacing requirement.
