Gibraltar 12934 3 Fixed Lifting Eye Bolt 4000 Lb 5/8-11

Product Description

The GIBRALTAR 12934 3 is a fixed lifting eye bolt with shoulder, rated for 4,000 lb lifting capacity and manufactured from Grade C-1035 forged steel. The shoulder design distributes load stress at the mounting surface, making it suitable for straight vertical lifts. The shank is fully threaded at 5/8-11 thread size with a 4-inch thread length and a 4-inch shank length. This hardware is installed by millwrights, riggers, maintenance mechanics, and industrial technicians working in manufacturing, construction, and heavy equipment service environments.

This eye bolt is designed for fixed-load, in-line vertical lifting applications where the load direction aligns with the bolt axis. The shoulder bears against the work surface to stabilize the connection and resist pull-through under rated load. It is commonly installed in steel fabrication, machinery rigging, structural lifting, and industrial maintenance scenarios where a permanent or semi-permanent anchor point is required. The 5/8-11 thread is a standard coarse-thread specification that mates with a wide range of tapped holes and hex nuts in both inch-system hardware applications.

Key Features

• 4,000 lb rated lifting capacity for vertical in-line loads
• Shoulder design seats against the work surface to prevent pull-through and distribute load stress
• Grade C-1035 forged steel construction for high tensile strength and toughness
• Fully threaded shank allows installation depth adjustment within the 4-inch thread length
• 5/8-11 coarse-thread specification for compatibility with standard inch-system tapped holes and fasteners
• 1-3/8 inch inside eye diameter accommodates shackles, hooks, and lifting hardware

Compatibility

Designed as an OEM-style fixed lifting eye bolt for use in inch-system applications requiring a 5/8-11 threaded anchor point with a shoulder base in steel, fabricated assemblies, or structural members.

Installation Notes

Installation is performed by qualified riggers, millwrights, or maintenance mechanics. Before installation, verify that the tapped hole thread depth and base material strength are rated to support the intended load. The eye bolt must be fully seated with the shoulder flush against the work surface before applying any load. Fixed eye bolts are rated for vertical in-line lifts only and must not be side-loaded or angularly loaded unless replaced with a swivel or angular-rated eye bolt.
