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.
