Steel Hex-Drive Shoulder Screws

Our strongest standard-fit shoulder screws. With the highest tensile strength, they withstand stress and mechanical loads that would break other materials, such as aluminum, nickel, and stainless steel. However, they do sacrifice corrosion resistance.

Black-Oxide Alloy Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

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 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.

Made-to-Order Same-Size Thread Stainless Steel Hex-Drive Shoulder Screws

Harness superior holding power with custom-shoulder-length screws that also won't rust. These are ideal for replacing fasteners in older machines or for testing prototypes. Threads that match the shoulder diameter give them a tighter hold than screws with a standard thread diameter. Use them in thicker materials and larger holes.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

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.
