National Mfg/spectrum Brands Hhi N220-889 Screw Hook

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N220-889 is a zinc-plated screw hook designed for overhead and wall-mounted hanging applications in residential and light commercial settings. Measuring 0.375 inches in diameter and 4.875 inches in length, this heavy-duty hook threads directly into wood framing, joists, studs, or similar substrates. It carries a rated load capacity of 150 pounds, making it suitable for suspending storage items, equipment, hanging baskets, and utility fixtures. The zinc finish provides corrosion resistance in moderately humid environments such as garages, sheds, and storage rooms. Typically installed by general contractors, carpenters, or maintenance technicians, the N220-889 ships in a bulk pack of 10 units per package.

This screw hook is used in a wide range of general fastening and hanging applications where a threaded fastener with a hook head is required. Common install scenarios include garage storage systems, workshop organization, utility shelving, and light fixture suspension in wood-framed structures. The bulk packaging makes it practical for jobs requiring multiple hook placements across a single area, reducing the need for multiple product orders. It is appropriate for both new construction and retrofit installations where the substrate is solid wood or similar material with adequate thread engagement depth.

Installation Notes

Installation is typically performed by carpenters, general contractors, or maintenance technicians using a standard drill or screwdriver with an appropriate bit or hook-turning tool. Always verify the substrate is solid wood or a material with sufficient density to support the rated 150-pound load before installing. Do not exceed the rated load capacity, and ensure adequate thread engagement depth to prevent pullout under load. Confirm the hanging application and substrate condition comply with any applicable local building or safety codes before use.
