National Mfg N179-158 Black Lag Bolt 1/4x1-1/2 in 5-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N179-158 is a 1/4-inch by 1-1/2-inch black lag bolt designed for use with decorative reinforcement hardware that features 1/4-inch hole sizes. The hex-shaped head is powder coated black to blend with decorative reinforcement pieces and deliver a clean, finished appearance. Installation requires a 3/8-inch wrench. Each package contains 5 lag bolts. This fastener is suited for light structural and decorative anchoring applications where a consistent black finish is required to match surrounding hardware.

This lag bolt is commonly used in residential and light commercial applications when securing decorative strap hinges, corner braces, and other ornamental reinforcement pieces to wood surfaces. The powder-coated hex head coordinates visually with black-finish hardware, making it a practical choice for fence gates, barn doors, shutters, and similar exterior or interior millwork installations.

Installation Notes

Installation is performed with a 3/8-inch wrench or appropriately sized socket. Pre-drilling a pilot hole into wood substrate is standard practice to prevent splitting and ensure proper seating. Follow applicable building codes when using lag fasteners in structural or load-bearing applications. Ensure the mating reinforcement piece is properly aligned before driving the bolt to final depth.
