About Shoulder Screws
More
Short-Thread Alloy Steel Shoulder Screws
Use these screws in thin materials; they have a shorter threaded portion than our standard shoulder screws. They’re 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.

18-8 Stainless Steel Shoulder Screws
Made from 18-8 stainless steel, these shoulder screws have good chemical resistance and may be mildly magnetic. A standard shoulder with an undersized tolerance allows them to fit most machinery and equipment. They’re often used to guide or align components, and as an axle or pivot point.
Black-oxide stainless steel screws have a matte-black finish.
