Lifting Eye Bolt

Lifting eye bolt performance should feel effortless, and our forged, certified hardware is engineered to make every hoist confident and controlled. Our lifting eye bolt gives crews a dependable anchor point that installs cleanly and performs under pressure. From shop floors to field lifts, our design helps reduce guesswork so teams can rig faster and lift smarter.

About the Product

Our lifting eye bolt is built for overhead lifting, rigging, and secure anchoring when a load needs a positive, steel-to-steel connection. Precision forging delivers strength you can trust, while clean threads and a properly formed shoulder help the bolt seat flush for predictable load transfer. 

We offer our lifting eye bolt in high-strength forged steel with options for protective finishes that resist corrosion in demanding environments. For washdown or marine exposure, stainless configurations provide long-term durability without sacrificing load rating. Multiple sizes and thread forms are available to match your rigging, shackles, and slings for a clean, compatible setup.

If your setup calls for an offset attachment, consider our Bent Eye Bolt; when a female-threaded lifting point is required, our Lifting Eye Nut is a compact, reliable alternative that pairs seamlessly with your existing studs and anchors.

DIN 580 Rated and Ready

This product follows the intent of DIN 580, which specifies forged eyebolts designed and rated for overhead lifting. The rounded head carries a stamped load rating for quick identification at the point of use, supporting better compliance and faster inspections. 

For best practice and load integrity, the eye must be installed so the shoulder seats fully and the eye aligns perpendicular to the lifting direction, helping the load track through the center of the eye rather than across its side.

Installation and Use

For safe performance, seat our lifting eye bolt against a flat, rigid surface and tighten until the shoulder is fully bearing; then verify that the eye aligns with the intended load line. Ensure full thread engagement in a base material with adequate strength, and recheck alignment after any repositioning or test lift. Avoid side-loading or shock loading, and apply appropriate load-angle reductions whenever a lift is not purely vertical.

Sizing and Compatibility

Choose the thread size and shank length that match your base material and required thread engagement; longer bodies help achieve full seating in thicker plates or castings. Our sizing spans common inch and metric threads, allowing you to standardize across equipment while keeping identification and inspection simple. If you need guidance, our team can help you match capacity, thread, and finish to your exact lifting plan.

FAQs

What exactly is an eye bolt used for?

An eye bolt provides a rated lifting or tie-down point so a hook, shackle, or sling can connect directly to the load. In overhead lifting, it creates a secure, fixed anchor that helps keep the rigging aligned and the force traveling through a known, tested path. When installed and used correctly, it supports controlled hoists, positioning, and transport of machinery, fabrications, and assemblies.

Should lifting eye bolts be tightened?

Yes—tighten the eye bolt until the shoulder seats firmly against a flat surface and the eye aligns with the intended load direction. Over-torquing can damage threads or distort seating, so focus on full seating and alignment rather than excessive torque. After the initial pull or test lift, recheck that seating and alignment have not shifted.

How much weight will an eye bolt hold?

Capacity depends on the specific size, material, and rating marked on the eye—use the stamped Working Load Limit on the head as the authoritative value. That rating applies to properly installed vertical lifts; any angular lift requires capacity reductions according to standard load-angle guidance. Never exceed the marked rating, and always ensure the base material and thread engagement can support the same or greater load.

How do you calculate lifting eye bolt load?

Start with the total load and how many lifting points share it, then account for sling angles and geometry. For multi-leg rigs, each eye typically sees the load divided by the number of legs, multiplied by the angle factor for the sling (as the angle decreases from vertical, the force on each leg—and each eye—increases).
