Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N221-259 is a zinc-plated eye bolt rated for a 160-pound load capacity. It measures 0.375 inches in diameter and 3 inches in length, making it a compact fastener suited for light-duty rigging, hanging, and securing applications. The eye bolt is sold in bulk packs of 10 units per package, which suits service professionals stocking hardware for multiple jobs. The zinc finish provides basic corrosion resistance for general interior and sheltered exterior use. Installers across multiple trades reach for this fastener when a reliable anchor point is needed for rope, wire, cable, or light chain runs.

This eye bolt is used in residential and light commercial settings wherever a threaded anchor point is required. Typical applications include securing cable runs, hanging fixtures, fastening guide wires, and mounting light rigging hardware to wood or compatible substrates. The 0.375-inch shank diameter fits standard pre-drilled or tapped holes in lumber framing, joists, and similar structural members. At a 160-pound rated load, it is appropriate for static or low-dynamic loads in general construction and maintenance work.

Installation Notes

Installation is typically performed by carpenters, electricians, plumbers, or general maintenance technicians depending on the application. Pre-drill a pilot hole sized to the shank diameter before threading into wood to prevent splitting. Do not exceed the rated 160-pound load capacity, and avoid dynamic or shock-load applications beyond the fastener rating. Consult applicable building codes for overhead rigging or load-bearing installations.
