Gibraltar SP11971 Shoulder Eye Bolt 1400 Lb 3/8-16

Product Description

The GIBRALTAR SP11971 is a shouldered lifting eye bolt rated for 1,400 lb capacity, designed for rigging and lifting applications in industrial, mechanical, and construction environments. Machined from grade C-1035 steel, the bolt features a 3/8-16 thread size with full threading along a 2.5-inch shank length. The shoulder design seats flush against the work surface, distributing load evenly and resisting angular pull better than a plain shank eye bolt. Rigging professionals, maintenance mechanics, and millwrights install this hardware when a secure, load-rated lift point is required on machinery, structural members, or equipment frames.

This eye bolt is suited for overhead lifting, hoisting, and tie-down applications where a threaded lift point is needed in steel or tapped assemblies. The 3/8-16 thread allows installation into standard tapped holes without special tooling. With a 1-inch inside eye diameter, the bolt accepts hooks, shackles, and rigging hardware common to light-duty to medium-duty lifting setups. It is appropriate for use in fabrication shops, maintenance bays, and field service environments where reliable, repeatable lift points are required.

Key Features

• 1,400 lb lifting capacity for reliable load-rated rigging
• Shoulder design distributes load at the work surface and resists angular loading
• Grade C-1035 steel construction for strength and durability
• Fully threaded 2.5-inch shank with 3/8-16 thread for standard tapped hole fitment
• 1-inch inside eye diameter accepts common hooks, shackles, and rigging hardware
• 1-21/32-inch outside eye diameter provides clearance for standard rigging connectors

Compatibility

Designed as an OEM-style replacement or direct-fit shoulder eye bolt for applications requiring a 3/8-16 threaded lift point in steel assemblies and tapped hole installations.

Installation Notes

Installation should be performed by a qualified mechanic or rigger familiar with load-rated hardware and applicable ASME B30 rigging standards. Thread the bolt fully into a properly sized and tapped hole until the shoulder seats flush against the work surface before applying any load. Never exceed the rated 1,400 lb lifting capacity, and inspect the eye bolt and threads for damage before each use. Ensure the lifting load is applied in line with the plane of the eye to maintain rated capacity.
