# What Are Lifting Eye Nuts Used For?

Nuts · DIN 582 · Application guide

Typical applications, the industries that specify lifting eye nuts, and how to choose the right size, material and finish for the joint.

Lifting Eye Nuts are used for providing a rated lifting or anchoring point on a threaded hole or stud, within a stated working load limit. They are manufactured to DIN 582, and selection is driven by the working load limit required, the applicable safety factor and the service environment.

- **Primary duty:** Providing a rated lifting or anchoring point on a threaded hole or stud, within a stated working load limit
- **Governing standard:** DIN 582
- **Thread size range:** M6 to M36
- **Category:** Nuts

Application notes are general engineering guidance. Verify the property class and any approval requirement against your own design calculation.

Application guide for Lifting Eye Nuts to DIN 582. The core duty of the type is providing a rated lifting or anchoring point on a threaded hole or stud, within a stated working load limit. The typical industries, the how-to-specify checklist, assembly practice and the exclusion cases are set out below. Stocked across roughly M6 to M36, they cover general to heavy-duty work.

## Typical Applications for Lifting Eye Nuts

The most common settings where these are specified:

- **Frames & weldments:** captive or welded options for repeatable assembly.
- **Overhead lifting:** threaded lifting points on studs and shafts.
- **Tensioning:** anchor points for turnbuckles and tie rods.
- **General machine building:** fastening covers, brackets, motors and sub-assemblies on production equipment.
- **Maintenance & repair (MRO):** a stocked size for servicing existing plant where the original fastener spec must be matched.

## How to Specify Lifting Eye Nuts for Your Application

- **Size:** Match the nominal size to the mating thread or hole. This product spans M6–M36; check the full table below for the exact dimensions of each size.
- **Locking & grade:** Match the strength grade to the bolt, and choose a locking style (nyloc, all-metal, serrated flange) if the joint sees vibration.
- **Environment:** For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
- **Standard:** This product is supplied to DIN 582. Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

## Installation & Assembly Practice

- Run the nut down by hand before applying the wrench to catch cross-threading early.
- Tighten the nut rather than the bolt head where access allows — the torque-to-preload relation is more consistent.
- For locking styles, note that nyloc inserts are single-use in critical joints and lose grip above roughly 120 °C.

## Common Selection Mistakes with Lifting Eye Nuts

- Pairing a high-class bolt with a lower-class nut — the nut strips before the bolt reaches proof load; the nut class must meet or exceed the bolt class.
- Using a plain nut with a spring washer in severe vibration instead of a prevailing-torque locking nut.
- Re-using nyloc nuts in critical joints.

## Where Lifting Eye Nuts Are Not the Right Choice

Not on their own — they need a matching bolt or stud — and a plain nut is not a substitute for a locking type under heavy vibration.

Custom manufacturing · Made to drawing

## Need a lifting eye nuts outside the standard range?

Dimensions, material, finish and form are specified from the drawing — a nut outside the standard range is a variation on existing tooling rather than a new design. Made by cold heading or tapping.

Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

Inside the plant

## Manufactured in our own plant

This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.

1. ![Wire rod feeding into a cold heading machine](https://engineeringhardware.com/wp-content/uploads/2026/08/09-wire-rod-feed-cold-heading-machine.webp) 01 **Cold heading** Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail. Head dimensions and under-head radius checked at set-up and per shift.
2. ![Thread rolling machine producing bolt threads](https://engineeringhardware.com/wp-content/uploads/2026/08/03-thread-rolling-machine-bolt-production.webp) 02 **Thread rolling** Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch. Go / no-go ring gauges to ISO 965 tolerance class 6g.
3. ![Baskets of bolts staged for heat treatment](https://engineeringhardware.com/wp-content/uploads/2026/08/05-heat-treatment-baskets-black-bolts.webp) 03 **Heat treatment** Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it. Core hardness and tensile tested per lot to ISO 898-1.
4. ![Zinc plated bolts in a treatment basket](https://engineeringhardware.com/wp-content/uploads/2026/08/23-zinc-plated-bolts-treatment-basket.webp) 04 **Surface treatment** Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list. Coating thickness and neutral salt spray hours to ISO 9227.

## Frequently Asked Questions

### Which industries use Lifting Eye Nuts?

They are commonly specified in bolted joints, vibration-prone equipment and frames & weldments, among other sectors.

### How do I choose the right size of Lifting Eye Nuts?

Match the nominal size to the mating thread or hole. This product is available from M6 to M36; the full dimension table on this page lists each size.

### Do Lifting Eye Nuts need a locking feature?

If the joint sees vibration or cyclic load, use a locking style (nyloc, all-metal lock, or serrated flange) or a thread-locking adhesive. For static joints a standard nut tightened correctly is usually sufficient.

### What material should Lifting Eye Nuts be for outdoor use?

For damp, coastal or chemical environments specify A4 (316) stainless or a suitably coated steel. For indoor or dry use, A2 (304) stainless or zinc-plated steel is normally adequate.

### Can I get a quote for Lifting Eye Nuts in the size and material I need?

Yes. Use the technical drawing and quote form on this page to set the size and options, then send the exact configuration to our team for pricing and lead time.
