Eye Nut
What is a Eye Nut?

An Eye Nut is a type of internally threaded fastener with a circular loop or “eye” on one end, designed primarily for lifting and rigging applications. It is screwed onto a bolt or threaded rod to provide an attachment point for slings, hooks, chains, or ropes. Eye nuts are engineered for vertical lifting or load-bearing operations, making them essential in construction, shipping, marine, and heavy industrial environments.
Built for strength and reliability, eye nuts ensure secure lifting and anchoring with the convenience of easy installation.
Key Features
- Load-Bearing Loop – Designed for vertical lifting and securing applications.
- Threaded Interior – Matches standard bolts or threaded rods.
- Heavy-Duty Construction – Built to handle high loads and tensile stress.
- Corrosion Resistant – Available in stainless steel, galvanized, and coated finishes.
- Multiple Styles – Includes DIN 582 (metric) and custom designs for different load directions.

Do you have questions?
What is the primary use of an eye nut?
Eye nuts are used for lifting, hoisting, or anchoring purposes by attaching hooks, slings, or cables to secure loads.
Can eye nuts be used for overhead lifting?
Yes, when rated and installed correctly, eye nuts (especially DIN 582 type) are safe for overhead lifting applications.
Are stainless steel eye nuts available?
Yes, we offer eye nuts in stainless steel 304 and 316 for superior corrosion resistance, especially in marine environments.
Do you provide test certificates for lifting hardware like eye nuts?
Absolutely. We supply eye nuts with load test certificates, material traceability, and compliance with international lifting standards.
