Description du produit
Crosby G-400 Eye Nuts are heavy-duty forged lifting attachments designed to provide a secure lifting point when used with threaded rods or bolts. Built for reliability, these eye nuts are commonly used in rigging, lifting, and material handling applications where strong, in-line lifting connections are required.
Manufactured from quenched and tempered forged steel, they offer excellent strength and durability, while the hot-dip galvanized finish provides corrosion resistance for long-term use in industrial environments.
Material:
Forged steel (quenched and tempered)
Hot-dip galvanized finish for corrosion resistance

UNC (imperial) threaded design
Tapped with standard UNC Class 2 threads after galvanizing
Working Load Limit range: approx. 520 lb to 40,000 lb depending on size
5:1 design factor (ultimate strength = 5× WLL)
Designed primarily for in-line (vertical) lifting applications
Meets or exceeds ASME B30.26 requirements
Available sizes: approx. 1/4" through 2" thread sizes
Each unit marked with identification and load rating
