Lifting Eye Bolt

A lifting eye bolt is a bolt with a loop at one end. It provides a secure point for attaching a hook, sling or rope when lifting or pulling a load.

A lifting eye bolt provides a ring for a sling, hook or shackle to attach to a load. It usually threads into a tapped hole or passes through a part and takes a nut on the other side. The eye takes a hook or shackle of a size that sits freely in the ring, and the thread matches the nut or hole it goes into.

Hot-dipped galvanising gives a thick zinc coating for outdoor and corrosive settings. Plain finish is bare metal with no added coating. PTFE coating offers low friction and some chemical resistance.

This kind of part is often made in steel, stainless steel 304, stainless steel 316 or brass. Stainless steel 316 gives better corrosion resistance than 304 for marine or chemical exposure. Brass is used where a non-sparking or decorative part is wanted.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a mill test certificate or a certificate of conformance for the material and finish. On receipt, check the thread form, the eye opening and the finish for damage. Confirm the markings match the grade and standard stated on the paperwork.
