Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N221-135 is a zinc-plated eye bolt designed for general fastening and rigging applications where a threaded loop anchor point is needed. Measuring 0.25 inches in diameter and 5 inches in length, this eye bolt carries an 80 lb load capacity. The zinc finish provides basic corrosion resistance for light-duty indoor and sheltered outdoor use. This bulk pack includes 20 units, making it a practical choice for contractors, maintenance crews, and supply stockrooms that need reliable quantities on hand.

This eye bolt suits residential and light commercial fastening tasks such as suspending conduit, hanging lighting fixtures, securing cables, or anchoring rope and cord runs. It is well-suited for interior applications where a fixed loop anchor point is required. The 0.25-inch shank diameter fits standard pre-drilled or tapped mounting locations. Trades that commonly install this hardware include electricians, plumbers, HVAC technicians, and general contractors working on equipment or wire management support structures.

Installation Notes

Eye bolts of this type are typically installed by hand-threading into a pilot hole sized for the shank diameter, then tightened with pliers or an appropriate wrench through the eye loop. Always verify the substrate material and fastener engagement depth support the rated load before applying tension. Do not exceed the 80 lb load rating. For overhead or critical suspension applications, consult applicable local building codes and confirm proper anchoring into structural material.
