Hillman Fasteners 230101 Hex Lag Bolt 3/8x5 in Zinc 50pk

Product Description

The HILLMAN FASTENERS 230101 is a zinc-plated hex head lag bolt supplied in a 50-piece pack. Lag bolts are heavy-duty wood fasteners used to secure structural members, ledger boards, decking, framing hardware, and heavy equipment mounts to wood substrates. The hex head drive allows installation with a standard socket wrench or impact driver. Each bolt measures 3/8 inch in diameter and 5 inches in length, making it suitable for applications requiring a deep bite into dimensional lumber or engineered wood.

This lag bolt is commonly used in residential and light commercial construction and renovation work. Typical applications include deck ledger attachment, pergola framing, fence post hardware, and general structural wood-to-wood fastening where a through-bolt is not practical. The zinc finish provides a baseline level of corrosion resistance suitable for dry and sheltered installations. Carpenters, framers, and general contractors are the primary installers.

Key Features

• 3/8 inch diameter x 5 inch length for deep structural engagement in dimensional lumber
• Hex head drive compatible with standard sockets and impact drivers
• Zinc finish for corrosion resistance in sheltered applications
• 50-piece pack format for bulk job-site use
• Wood-thread form designed for direct drive into pilot-bored lumber

Compatibility

Designed as a standard 3/8 inch hex head lag bolt suitable for wood-to-wood and hardware-to-wood structural fastening applications in residential and light commercial construction.

Installation Notes

Lag bolts of this diameter and length typically require a pilot hole bored to the appropriate shank and thread diameter before installation to prevent wood splitting. Install using a socket wrench or impact driver rated for the fastener size. Follow applicable building codes, including IRC or IBC guidelines, for structural fastener spacing and load requirements. Do not overtorque, as this can strip the wood thread engagement or fracture the fastener.
