Gibraltar 12911 4 Fixed Shoulder Eye Bolt 3200 Lb 9/16-12

Product Description

The GIBRALTAR 12911 4 is a fixed lifting eye bolt with a shoulder, designed for vertical and in-line load lifting applications in industrial and commercial environments. Forged from C-1035 steel, this eye bolt carries a working load capacity of 3,200 pounds and features a fully threaded shank measuring 3 inches in length on a 9/16-12 thread. The shoulder provides a positive bearing surface against the load member, preventing the eye from pulling through and ensuring consistent load transfer. This hardware is typically installed by millwrights, ironworkers, riggers, and maintenance mechanics working with overhead lifting systems, hoists, and rigging assemblies.

This eye bolt is suited for use in fixed-point vertical lifting setups where angular loading is not intended. The shoulder design makes it appropriate for installation through plates, beams, or structural members where a flush bearing surface is required. Applications include machinery positioning, equipment hoisting, and anchor point installation in manufacturing facilities, construction sites, and maintenance shops. The 9/16-12 thread size fits standard hardware used across a wide range of industrial lifting and rigging setups.

Key Features

• 3,200 pound lifting capacity rated for fixed, vertical in-line loading
• Shoulder design provides positive bearing surface and prevents pull-through
• Forged C-1035 steel construction for strength and durability under load
• Fully threaded 3-inch shank on a 9/16-12 thread for secure fastening
• Eye inside diameter of 1-9/32 inches accommodates standard hooks and shackles
• Inch measurement system for compatibility with standard American rigging hardware

Compatibility

Designed as an OEM-style replacement or standard hardware addition for fixed-point vertical lifting applications using 9/16-12 threaded mounting points in industrial and commercial rigging setups.

Installation Notes

Installation should be performed by a qualified rigger or millwright familiar with applicable ASME B30 rigging standards. Always ensure the threaded hole or nut is properly sized for the 9/16-12 thread and that the shoulder seats flush against the load surface before applying any load. This eye bolt is rated for vertical, in-line lifting only — angular or side loading will reduce rated capacity and may cause failure. De-energize, unload, and secure all equipment before installing or removing lifting hardware.
