National Mfg N220-723 Lag Screw Eye 7/16x5-1/4 in Zinc

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N220-723 is a zinc lag screw eye designed for overhead and lateral load applications in residential and light commercial construction. Measuring 7/16 inches in diameter and 5-1/4 inches in length, this lag-thread fastener drives directly into wood framing or structural members without a pre-tapped hole, providing a secure fixed loop anchor point. With a rated holding capacity of 320 pounds, it is suited for hanging fixtures, cable runs, rope guides, and similar suspended load applications. Installers working in framing, general construction, or maintenance will find this a standard-use hardware item.

This lag screw eye is appropriate for wood-framed residential and light commercial structures where a threaded loop anchor is needed. Typical installations include attaching support cables, conduit hangers, rope systems, or suspended fixtures to joists, rafters, studs, or beams. The zinc finish provides a degree of corrosion resistance suitable for interior and protected exterior environments. This item ships in bulk quantities of 10 units per package.

Installation Notes

A licensed carpenter, contractor, or qualified tradesperson should verify that the receiving wood member is sound, properly sized, and capable of sustaining the intended load before installation. Pre-drilling a pilot hole slightly smaller than the shank diameter is standard practice to prevent wood splitting and ease driving. Load ratings apply to properly installed fasteners in structurally adequate wood; overhead or safety-critical applications should be engineered accordingly. Follow applicable building codes for fastener selection and load calculations.
