Hillman Fasteners 230024 Hex Head Lag Bolt 1/4x3-1/2 Zinc 100pk

Product Description

The HILLMAN FASTENERS 230024 is a zinc-plated hex head lag bolt designed for heavy-duty wood fastening applications. Each bolt measures 1/4 inch in diameter and 3-1/2 inches in length, providing solid thread engagement for structural and general carpentry connections. The hex head drive accepts standard wrenches and sockets, making installation straightforward for both trade professionals and experienced DIYers. This package contains 100 bolts, making it suitable for production framing, decking, ledger attachment, and similar high-volume fastening tasks where consistent hardware supply is essential.

Hex head lag bolts of this size are commonly used in residential and light commercial construction, including wood-to-wood connections in framing, deck ledger boards, fence posts, pergola structures, and structural lumber assemblies. The 1/4 x 3-1/2 inch dimension is a widely specified size for applications requiring a secure mechanical connection through dimensional lumber or engineered wood. This 100-count box is well-suited for contractors and installers working on projects requiring repetitive lag fastening.

Key Features

• Zinc plating provides corrosion resistance for indoor and protected outdoor applications

Compatibility

Designed as a standard hex head lag bolt for use in wood-to-wood and wood-to-structural-member fastening applications where a 1/4 x 3-1/2 inch zinc lag bolt is specified.

Installation Notes

Lag bolts of this size are typically installed by carpenters, framers, deck builders, and general contractors. Always pre-drill a pilot hole sized to the bolt shank to prevent wood splitting and reduce installation torque. Use a hex socket or box wrench rather than an adjustable wrench to maintain consistent drive and avoid fastener rounding. Follow applicable building code requirements, including IRC or IBC provisions, for structural lag bolt spacing, edge distance, and end distance when used in load-bearing assemblies.
