National Marker N220814 Stainless Steel Screw Hook

Product Description

The NATIONAL MARKER N220814 is a stainless steel screw hook designed for marine and outdoor applications where corrosion resistance is essential. Measuring 0.25 inches in diameter and 4.25 inches in length, this hook features a lag screw thread for secure fastening into wood and similar substrates. Its stainless steel construction provides long-term durability in wet, salt-air, and other harsh environments. Licensed tradespeople and experienced DIYers working on docks, boat hardware, exterior structures, and similar projects rely on hardware like this for dependable holding strength without rust degradation over time.

This screw hook is suited for marine installations, outdoor structures, and general-purpose fastening tasks where exposure to moisture or corrosive conditions is expected. The lag screw thread design allows it to be driven directly into wood framing, deck structures, or exterior trim without a separate nut or anchor. It is sold individually, making it easy to source specific quantities for repair and maintenance work.

Installation Notes

A pilot hole is recommended before driving this screw hook into hardwood or dense lumber to prevent splitting and reduce installation torque. Power down or de-energize any adjacent systems before working in proximity to electrical components. Use appropriate hand tools or a low-speed drill to seat the hook fully without over-driving. Follow applicable building and marine hardware standards for load-bearing and structural fastening applications.
