Stainless Steel Hex-Drive Shoulder Screws

These screws hold up against moisture and chemicals better than their steel counterparts, but they aren't as strong.

Check out our Made-to-Order Stainless Steel Hex-Drive Shoulder Screws if you don't see the shoulder length you need.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these screws won't degrade when exposed to harsh weather, salt water, and most chemicals.

Highly Corrosion-Resistant Black-Oxide 316 Stainless Steel—Combines a finished appearance with the rust resistance of 316 stainless steel. Even if the coating wears off, these screws will hold up against corrosive agents in most environments, including salt water and most chemicals.

Eyebolts—For Lifting

Create a secure attachment point for hooks, shackles, and other lifting equipment. Also known as machinery eyebolts, these eyebolts are used to lift heavy machines and materials. They have a closed eye that won’t bend under strain.

Warning: Never use to lift people or items over people. Capacities listed are for vertical lifting only.

Steel

With

Shoulder

With Shoulder—Use for lifting at angles up to 45° or for vertical lifting. Because angular lifting significantly reduces the eyebolt’s capacity, we recommend hoist rings for heavy loads.

Galvanized Steel

With

Shoulder

Galvanized steel eyebolts have a hot-dipped finish for more corrosion resistance than zinc-plated steel.

With Shoulder—Use for lifting at angles up to 45° or for vertical lifting. Because angular lifting significantly reduces the eyebolt’s capacity, we recommend hoist rings for heavy loads.

Rotating Eyebolts—For Lifting

Unlike conventional eyebolts, you can rotate the eye 360° to match the angle of your load.

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.

Powder-Coated Steel

Powder-coated steel eyebolts are impact resistant, but less corrosion resistant than stainless steel eyebolts. They include a removable key for tightening the bolt.

Closed Eye—Closed eyes are stronger than bent-closed eyes.
