About Shoulder Screws
More
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.
For technical drawings and 3-D models, click on a part number.
For made-to-order shoulder screws, please specify the shoulder length in 0.01” increments.
Same-Size Thread 18-8 Stainless Steel Shoulder Screws
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.
