Alloy Steel Shoulder Screws

Comparable to Grade 8 steel, these alloy steel shoulder screws are the strongest 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.

316 Stainless Steel Shoulder Screws

More corrosion resistant than 18-8 stainless steel shoulder screws, these have excellent resistance to chemicals and salt water. They 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.
