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.

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.

Eyebolts—For Lifting
Also known as machinery eyebolts.
Zinc-plated steel eyebolts offer good corrosion resistance.
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.
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.
Warning: Never use to lift people or items over people.

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.

Low-Visibility Eyebolts—For Lifting
The matte black-oxide finish won't reflect light, allowing the eyebolts to blend into the background.
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.

Low-Temperature Eyebolts—For Lifting
These eyebolts retain their strength in temperatures as low as -40° F.
