Lifting Eye Nut

A lifting eye nut is a nut with a loop or eye formed on one end. It provides a threaded attachment point for lifting gear such as hooks, shackles or slings.

A lifting eye nut provides a threaded attachment point for lifting gear. It takes a hook, shackle or sling, and it often screws onto a threaded stud or bolt of the same thread and class.

Hot dip galvanising gives a thick zinc coating for outdoor and corrosive conditions. Plain finish has no added coating and is often chosen for indoor use or where a coating would interfere. PTFE coating gives low friction and some chemical resistance.

This kind of nut is often made in steel, stainless steel 304, stainless steel 316 or brass. Steel grades give high strength and suit general lifting. Stainless steel 304 and 316 resist corrosion, with 316 better for marine or chemical exposure.

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 certificate of conformance for the material and grade. On receipt, check the thread form, eye dimensions and any coating for damage. Confirm the markings match the grade ordered.
