National Marker N220723 Zinc Lag Screw Eye

Product Description

The NATIONAL MARKER N220723 is a zinc-finish lag screw eye designed for secure fastening applications in trade and construction environments. This hardware fastener combines a threaded lag screw shank with a formed eye loop, allowing it to anchor into wood substrates while providing a fixed attachment point for wire, rope, hooks, or other hardware. The steel construction with zinc finish provides corrosion resistance for indoor and light-duty outdoor use. At 7/16 inches in diameter and 5-1/4 inches in length, this screw eye suits medium-load anchoring tasks. It is part of the catalog model 2150BC series and is sold individually.

This lag screw eye is suited for residential and light commercial applications where a threaded anchor point is needed in wood framing, joists, beams, or structural lumber. Common install scenarios include hanging equipment supports, cable management anchors, safety tie-off rings, and fixture mounts. Tradespeople working in electrical, HVAC, plumbing, and general construction regularly use lag screw eyes to secure conduit hangers, pipe straps, and service lines to overhead or lateral wood members.

Key Features

• Steel construction with zinc finish for corrosion resistance
• 7/16 inches shank diameter provides solid thread engagement in wood
• 5-1/4 inches overall length suits medium-depth anchoring applications
• Formed eye loop offers a fixed attachment point for wire, rope, or hooks

Compatibility

Designed as a standard lag screw eye for use in wood substrates; compatible with typical anchoring and hanging hardware used in residential and light commercial construction and trade service work.

Installation Notes

Installation is performed by drilling a pilot hole into the wood substrate before driving the lag screw eye to prevent splitting. A pilot hole sized to approximately 75 percent of the shank diameter is standard practice. Use a wrench or rod through the eye loop to apply torque evenly. Avoid over-driving, which can strip threads or deform the eye; stop when the eye is oriented to the intended load direction.
