Ace the EPRI Rigger's Challenge 2026 – Lift Your Career to New Heights!

The defining feature of eyenuts is the looped head that forms an eye for rigging. This loop provides a built-in attachment point for hooks, slings, or ropes, making the nut suitable for lifting or securing loads. The threaded portion still screws onto a bolt or stud like a regular nut, but the eye distinguishes it and enables quick rigging connections. The other shapes described—hex head, square head, or slotted head—refer to different drive styles on ordinary nuts or screws and do not provide the lifting eye feature that characterizes eyenuts.
