Gibraltar P41391GB Forged Eye Bolt 5/16 Galvanized

Product Description

The GIBRALTAR P41391GB is a forged steel eye bolt with a hot-dipped galvanized finish, designed for wood screw installation in structural and rigging applications. The 5/16-inch threaded shank provides a secure anchor point for hooks, cables, rope, or chain attachments. A 2-inch thread length and 2.25-inch shank length allow reliable engagement in dimensional lumber and timber framing. The hot-dipped galvanization delivers a thick zinc coating that resists corrosion in outdoor and high-humidity environments. This eye bolt is sold individually and is a standard fastener installed by contractors, riggers, and maintenance professionals across residential and light commercial job sites.

This eye bolt is suited for overhead and lateral tie-off points in wood framing, decking, pergolas, swing sets, and utility structures. The forged steel construction handles dynamic and static loads better than cast alternatives, making it appropriate where load integrity matters. The 5/8-inch inner diameter opening accommodates common hardware such as shackles, carabiners, turnbuckles, and quick links. Installation into structural lumber is a typical application for this style of fastener.

Installation Notes

This eye bolt is installed by contractors, riggers, or maintenance technicians working with wood substrates. Pre-drill a pilot hole sized appropriately for the 5/16-inch thread to prevent splitting the lumber, especially in hardwoods or near board ends. Ensure the eye bolt is threaded fully to the shoulder before applying load. Follow applicable load ratings and applicable building codes for overhead or structural tie-off applications.
