Description
The NATIONAL MFG/SPECTRUM BRANDS HHI N220-822 is a stainless steel screw hook rated to hold up to 220 pounds. At 3/8 inch diameter and 4-7/8 inches in length, this hook is built for demanding load-bearing applications where corrosion resistance is a priority. The stainless steel construction makes it well suited for outdoor, marine, and high-humidity environments where standard zinc or carbon steel hardware would corrode prematurely. This package contains 10 hooks, making it practical for contractors, maintenance crews, and facility technicians who need consistent, reliable fasteners in quantity.
These screw hooks are appropriate for a wide range of commercial and residential applications including suspended shelving, equipment hanging, cable routing, and utility installations. The 220-pound load rating per hook supports meaningful structural use beyond light-duty picture hanging or decorative tasks. Plumbers, HVAC technicians, and electricians frequently use screw hooks of this size for pipe hangers, conduit support, and equipment anchoring in mechanical rooms, crawlspaces, and utility areas where moisture exposure is common.
Key Features
- 220-pound load capacity suitable for structural and equipment-hanging applications
- Stainless steel construction resists corrosion in wet, coastal, and outdoor environments
- 3/8 inch shank diameter provides solid bite and pull-out resistance in wood substrates
- 4-7/8 inch overall length accommodates thicker framing members and layered materials
- Sold in a 10-count box for contractor-quantity purchasing
Compatibility
Designed as a general-purpose screw hook for use in wood framing, joists, and structural lumber where a threaded hook anchor is required. No specific system compatibility is stated by the manufacturer for this part.
Installation Notes
Screw hooks of this size are typically installed by hand-starting the threaded tip into a pilot hole, then using a bar or rod through the hook eye to apply torque for full seating. A pilot hole is recommended to prevent wood splitting, particularly in hardwoods or engineered lumber. Always verify the substrate is rated for the intended load before hanging equipment or materials. Confirm the anchor point, not just the hook, meets the load requirements of the application.
