Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N221-002 is a zinc-plated screw hook designed for medium-weight to heavyweight hanging applications. It measures 3/8 inches in diameter and 10 inches in length, featuring lag screw threads for secure installation into wood substrates. The hook carries a safe working load of 150 pounds, making it suitable for planters, signs, clotheslines, and similar suspended loads. Sold in a bulk pack of 10 units, this hardware is a standard item for contractors, maintenance professionals, and property managers handling routine fastening and hanging tasks.

This screw hook is appropriate for residential and light commercial use where a reliable, corrosion-resistant hanging point is needed. Common applications include outdoor planters, signage, clotheslines, and general utility hanging in garages, workshops, or storage areas. The zinc finish provides basic corrosion resistance for covered outdoor and indoor environments. Do not use for overhead lifting, support of human weight, or athletic and playground equipment. When safety is a factor in the application, consult the manufacturer before installation and inspect the hardware frequently after installation.

Installation Notes

Installation is typically performed by a general contractor, maintenance technician, or qualified tradesperson using standard hand tools. Pilot drilling is recommended to prevent wood splitting, particularly in hardwood or treated lumber. Confirm that the anchor substrate can support the intended load before hanging any object. Never exceed the 150-pound safe working load, and do not use this hardware for overhead lifting, support of human weight, or athletic or playground equipment.
