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 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.

Eyebolts—For Lifting
Also known as machinery eyebolts.
Zinc-plated steel eyebolts offer good corrosion resistance.
304 stainless steel eyebolts are more corrosion resistant than galvanized steel.
Note: Capacities listed are for vertical lifting only. Eyebolts with shoulder can be used for angular lifting up to 45°, but the capacities will be significantly reduced. For angular lifting, we recommend Hoist Rings.
Warning: Never use to lift people or items over people.

Eyebolts with Nuts—For Lifting
Also known as nut eyebolts, these are designed for through-hole applications.
Galvanized steel eyebolts have a hot-dipped finish for corrosion resistance.
304 stainless steel eyebolts are more corrosion resistant than galvanized steel.
316 stainless steel are the most corrosion resistant eyebolts.
Note: Capacities listed are for vertical lifting only. Eyebolts with shoulder can be used for angular lifting up to 45°, but the capacities will be significantly reduced. For angular lifting, we recommend Hoist Rings.

Rotating Eyebolts—For Lifting
Unlike conventional eyebolts, you can rotate the eye 360° to match the angle of your load.
Powder-coated steel eyebolts are impact resistant, but less corrosion resistant than stainless steel eyebolts. They include a removable key for tightening the bolt.
Note: Capacities listed are for vertical lifting only. Eyebolts with shoulder can be used for angular lifting up to 45°, but the capacities will be significantly reduced. For angular lifting, we recommend Hoist Rings.
Warning: Never use to lift people or items over people.
