Gibraltar 16280 7 Lifting Eye Nut 3600 Lb 5/8-11 Thread

Product Description

The GIBRALTAR 16280 7 is a regular-duty lifting eye nut rated at 3,600 pounds capacity, designed for use with threaded rod, bolts, or studs where an attachable lifting or rigging point is required. Manufactured from Grade C-1030 carbon steel with a self-colored finish, this eye nut provides a durable, cost-effective solution for overhead lifting, tensioning, and load-securing applications. The 5/8-11 thread size is a widely used unified coarse pitch that fits standard threaded fasteners. Weighing 0.62 pounds, it is compact enough for repeated field use while maintaining the structural integrity required for rated load applications.

This eye nut is suited for industrial, construction, mechanical, and maintenance environments where a threaded lifting point must be attached to equipment, structural members, or rigging assemblies. Typical applications include hoisting machinery, securing loads to overhead anchor points, and providing attachment points on fabricated steel structures. The regular-duty classification makes it appropriate for general-purpose rigging tasks that fall within the rated working load limit. Installation and use should comply with applicable ASME B30 rigging standards and facility safety protocols.

Key Features

• 3,600 lb rated lifting capacity for regular-duty overhead rigging
• 5/8-11 unified coarse thread for compatibility with standard threaded fasteners
• Grade C-1030 carbon steel construction for strength and durability
• Self-colored finish — no coating to measure or maintain
• 3-3/16 inches overall height with 1-1/2 inches inside eye diameter and 2-1/2 inches outside eye diameter
• 2-1/2 inches bell/base width for stable seating on the bearing surface

Compatibility

Designed to thread onto any standard 5/8-11 bolt, stud, or threaded rod. Suitable for use with shackles, hooks, or wire rope fittings that fit the 1-1/2 inch inside eye diameter.

Installation Notes

Installation should be performed by a qualified rigger or millwright familiar with ASME B30 rigging standards. Thread the eye nut fully onto the fastener until the base seats flush against the load surface before applying any load. Never exceed the rated 3,600 lb working load limit, and inspect the eye nut for deformation, cracks, or thread damage before each use. Remove from service immediately if any damage is found.
