With threads the same diameter as the shoulder, these screws can handle heavy loads. Made of alloy steel, they are comparable in strength to Grade 8 steel. A standard shoulder with an undersized tolerance allows them 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.
