These shoulder screws come with a traceable lot number and material test report. Comparable to Grade 8 steel, they are the strongest shoulder screws we offer. They have a standard shoulder with an undersized tolerance to fit most machinery and equipment. Also known as stripper bolts, they're commonly used in punch and die assemblies, and as an axle or pivot point.
