Gibraltar 12251 1 Fixed Blank Lifting Eye Bolt with Shoulder

Product Description

The GIBRALTAR 12251 1 is a fixed blank lifting eye bolt with a shoulder, manufactured from grade C-1035 forged steel. Designed for rigging and lifting applications, this eye bolt features a 3-inch shank length and a shouldered base that distributes load and resists angular pull when properly seated against a mounting surface. The eye inside diameter measures 1 inch, providing a consistent attachment point for hooks, shackles, or wire rope. Installed by millwrights, riggers, maintenance mechanics, and industrial tradespeople, this bolt is suited for use in fixed lifting point setups where a permanent or semi-permanent anchor is required.

This eye bolt is appropriate for use in industrial, commercial, and heavy-duty maintenance environments where fixed overhead or structural lifting points are needed. The shouldered design is intended for installations into flat or flanged surfaces where the shoulder base can fully contact the mounting surface, ensuring proper load transfer. It is a standard inch-measurement fastener compatible with common inch-series rigging hardware and tooling.

Key Features

• Fixed blank eye bolt style — no threaded shank, suitable for custom or press-fit installations
• Shoulder design distributes load and resists side-angle forces at the mounting surface
• Grade C-1035 forged steel construction for strength and durability under lifting loads
• 1-inch eye inside diameter accommodates standard hooks, shackles, and rigging hardware
• 3-inch shank length provides adequate grip length for structural mounting applications
• Inch measurement system — compatible with standard inch-series rigging and fastener tooling

Compatibility

Designed as an OEM-style fixed blank lifting eye bolt for use with inch-series rigging hardware in industrial and commercial lifting applications where a shouldered eye bolt anchor point is required.

Installation Notes

Installation should be performed by a qualified rigger, millwright, or maintenance mechanic familiar with applicable rigging and lifting standards. Before installation, de-energize, de-pressurize, or otherwise make safe any equipment or structure being worked on. Ensure the mounting surface is flat and that the shoulder base contacts the surface fully before applying any load. Never side-load a fixed lifting eye bolt beyond the rated capacity, and always verify that the rigging hardware used is rated to match or exceed the intended load.
