Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N221-226 is a zinc-plated eye bolt designed for light-duty fastening and rigging applications. At 5/16 inch in diameter and 4 inches in length, it provides a threaded shank with a looped head for attaching hooks, cables, ropes, or chains to a fixed surface. The zinc finish provides basic corrosion resistance for indoor and sheltered outdoor use. Rated at a 90 LB load capacity, this eye bolt is suited for light suspension and tie-down tasks in residential, commercial, and workshop settings. Installation is straightforward and does not require specialized trade tools.

This eye bolt is commonly used in general construction, woodworking, shelving, and light rigging applications. The 5/16 inch shank threads into pre-drilled holes in wood, metal, or similar substrates. It is packaged in bulk quantities of 10 units per package, making it practical for contractors or technicians who need multiple fasteners on a single job. Typical end users include general contractors, maintenance technicians, and skilled tradespeople requiring a reliable, standardized fastener for hanging or anchoring loads within the rated capacity.

Installation Notes

Installation should be performed by a qualified tradesperson or knowledgeable individual familiar with fastener load ratings and substrate requirements. Always pre-drill a pilot hole sized appropriately for the 5/16 inch shank before installation to avoid splitting or substrate damage. Never exceed the 90 LB rated load capacity, and ensure the eye bolt is fully threaded into a structurally sound substrate before applying load. Follow applicable building codes and load-bearing guidelines for the specific application.
