Malaxy Eye Nuts (also known as lifting eye nuts or ring nuts) are high-strength internally threaded fasteners featuring a circular loop (“eye”) at one end. Designed primarily for lifting, rigging, and anchoring applications, they are screwed onto a bolt or threaded rod to provide a secure attachment point for slings, hooks, chains, wire ropes, or cables. As a trusted manufacturer and supplier in the fastener industry, Malaxy offers premium-quality eye nuts manufactured to international standards for global industrial use.
Key Features
Forged Construction: Drop-forged from carbon steel or stainless steel for superior strength and durability—ideal for heavy-duty lifting and rigging.
Corrosion Resistance: Available in zinc-plated, hot-dip galvanized, stainless steel A2 (304) and A4 (316) finishes for marine, outdoor, and chemical environments.
High Load Capacity: Working Load Limits (WLL) range from 0.07 tonnes to over 50 tonnes, with a safety factor of 4:1 or 5:1 as per lifting standards.
Wide Compatibility: Metric (M6–M100), UNC, UNF, and BSW thread types available to meet diverse application requirements.
Quality Assured: Manufactured and tested in accordance with ISO 9001:2015, with EN 10204 3.1 test certificates and CE marking available.
Easy Installation: Simple screw-on design allows for quick attachment and removal, making them ideal for temporary or adjustable rigging setups.

Safety & Installation Guidelines
Ensure the eye nut is fully screwed onto the threaded rod or bolt with complete thread engagement.
The mating surface must be clean, flat, and of equal or greater strength than the eye nut material.
For vertical lifting only. Angular lifting significantly reduces load capacity—refer to manufacturer’s angular load reduction charts.
Never exceed the rated Working Load Limit (WLL). Use a safety factor appropriate for the application.
Regular inspection for wear, deformation, or corrosion is required for continued safe operation.
Operating temperature range: -20°C to +200°C for standard carbon and stainless steel grades.
