With threads the same diameter as the shoulder, these screws can handle heavy loads. Made from 18-8 stainless steel, they 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.
