National Mfg N220-814 Ss Screw Hook 50 Lb 10-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N220-814 is a stainless steel screw hook rated to hold up to 50 pounds. Measuring 0.25 inches in diameter and 4.25 inches in length, this hook threads directly into wood framing, studs, or structural members to provide a secure hanging or retention point. The stainless steel construction resists corrosion, making it suitable for wet, humid, or outdoor environments where a zinc or zinc-plated fastener would degrade. Each package contains 10 hooks, sold in boxed bulk format. Plumbers, HVAC technicians, and general trade contractors frequently use screw hooks to route and support pipe, conduit, tubing, or hose runs overhead or along wall framing.

This screw hook is appropriate for light-duty support and hanging applications in both residential and light commercial settings. Common uses include supporting copper or PVC pipe runs, securing flex duct hangers, hanging tools or equipment in mechanical rooms, and general utility fastening tasks. The 50-pound load rating per hook makes it practical for single-pipe or single-conduit support spans at standard joist intervals. The 10-piece pack quantity suits service technicians stocking a van or completing a single rough-in job.

Installation Notes

A licensed tradesperson or experienced installer should pilot-drill a starter hole slightly smaller than the shank diameter before threading the hook into the substrate to prevent wood splitting. Always verify the mounting substrate can support the intended load before hanging pipe, conduit, or equipment. Power down or de-energize any nearby electrical systems before working overhead in panel rooms or electrical spaces. Follow applicable codes, including NEC or IPC guidelines, when using screw hooks to support conduit or pipe runs.
