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.

Same-Size Thread Alloy Steel Shoulder Screws
With threads the same diameter as the shoulder, these screws can handle heavy loads. Made of alloy steel, they are 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.
Passivated stainless steel screws have added protection against oxidation and corrosion.
Black-oxide stainless steel screws have a matte-black finish.

Same-Size Thread 18-8 Stainless Steel Shoulder Screws
Uncoated
Black Oxide
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.

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.

Alloy Steel Thread-Locking Shoulder Screws
A locking element on the threads adds friction to resist loosening. 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.

18-8 Stainless Steel Thread-Locking Shoulder Screws
A locking element on the threads adds friction to resist loosening. These 18-8 stainless steel shoulder screws have good chemical resistance and may be mildly magnetic. All are passivated for added protection against oxidation and corrosion. 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.
