National Marker N220707 Zinc Lag Screw Eye

Product Description

The NATIONAL MARKER N220707 is a zinc-finished lag screw eye designed for secure fastening applications where corrosion resistance and holding strength are required. The lag screw eye measures 0.375 inches in diameter and 4.5 inches in length, making it well suited for medium-duty anchoring tasks. Constructed from steel with a zinc finish, it provides a durable combination of tensile strength and surface protection against oxidation. This fastener type is commonly installed by general contractors, electricians, and maintenance tradespeople as a reliable anchor point for hanging conduit, wire, cable, chain, or similar suspended loads.

The N220707 lag screw eye is appropriate for residential and light commercial applications. It installs directly into wood framing, joists, rafters, and similar structural members where a threaded eye anchor is needed. The lag thread profile bites into wood without requiring a through-bolt, keeping installation straightforward in overhead or wall-mounted scenarios. Typical uses include supporting cable trays, hanging sign hardware, routing wire rope, and anchoring fixtures in utility spaces.

Key Features

• Steel construction with zinc finish for corrosion resistance in dry and semi-exposed environments
• 0.375-inch shank diameter provides solid holding capacity in wood substrates
• 4.5-inch length offers deep thread engagement for improved pull-out resistance
• Catalog series 2150BC — bulk box pack for multi-unit jobsite use
• Lightweight at 0.191 pounds per unit, minimizing load contribution in suspended applications

Compatibility

Designed as a standard lag screw eye for installation into wood framing members in residential and light commercial construction and maintenance applications.

Installation Notes

Installation is performed with a drill and appropriately sized pilot bit to prevent wood splitting — pilot holes are strongly recommended when working near the end grain or in hardwood substrates. Power down or de-energize any nearby electrical circuits before drilling into wall cavities or overhead framing. Do not exceed the load rating of the anchor point or the structural member into which the lag screw eye is installed. Follow applicable building codes for the jurisdiction when using lag fasteners in structural or load-bearing configurations.
