Stainless Steel Screw Hook
This National Mfg. screw hook is a corrosion-resistant fastener made from stainless steel with a lag screw thread. It suits outdoor and marine projects where moisture would damage ordinary steel hardware. The bulk box packaging supports trade and high-volume DIY work. Model number 2153 identifies the design.
Upgrading from zinc or plain steel hooks
Builders replace zinc-plated or bare steel hooks with this stainless version when the installation faces salt air, pool chemicals or constant damp. The jump is worth it whenever a rusted hook would mean rework, stained timber or a safety risk. The lag thread drives directly into wood without a separate anchor.
Build integration: wood substrates and load points
The hook threads into structural timber, fence posts or deck joists, so the surrounding material must be sound enough to hold the threaded portion. Its open eye frees up the connection point for chain, rope or wire attachments. Stainless construction eliminates the need for sacrificial coatings or frequent replacement cycles.

Questions about this item
What size pilot hole is needed for the 1/4" lag screw thread on the N220814 hook?
Drill a pilot hole slightly smaller than the 1/4" wire diameter; the thread length is 1-1/2" so the hole must be at least that deep in solid wood.
What is the most common installation mistake with the N220814 stainless steel screw hook?
Driving the hook without a pilot hole or using an oversized bit, which strips the 1/4" lag threads and reduces holding power in the wood.
Will the N220814 stainless steel hook need replacement due to corrosion?
The stainless steel material resists corrosion, so the hook itself will not need replacement from rust; inspect the wood mounting point periodically for rot.
