Hillman Fasteners 230086 Hex Head Lag Bolt 3/8x2-1/2 Zinc 50PK

Product Description

The HILLMAN FASTENERS 230086 is a zinc-plated hex head lag bolt supplied in a 50-piece pack. Lag bolts are heavy-duty wood screws driven with a wrench rather than a screwdriver, making them the standard fastener for structural wood connections, ledger boards, framing, and heavy timber applications. The 3/8-inch diameter and 2-1/2-inch length suit mid-range structural loads where a through-bolt is not practical. The zinc plating provides basic corrosion resistance suitable for indoor and sheltered outdoor use. These are driven with a 9/16-inch hex wrench or socket.

These lag bolts are used in residential and light commercial construction, deck framing, ledger attachment, wood-to-wood structural connections, and general carpentry. The 50-piece pack quantity suits job-site use where multiple fasteners are needed per connection point. Carpenters, framers, deck builders, and general contractors are the primary installers. The hex head allows consistent torque application with standard socket sets, reducing the risk of cam-out during installation.

Key Features

• 3/8-inch diameter x 2-1/2-inch length for mid-range structural wood connections
• Zinc plating for basic corrosion resistance in dry and sheltered environments
• Hex head drive accepts standard 9/16-inch socket or wrench
• 50-piece pack quantity supports multi-fastener structural assemblies
• Heavy-duty lag thread pattern for high pull-out resistance in wood substrates

Compatibility

Designed for use in wood-to-wood structural connections where a 3/8-inch lag bolt is specified by plan or code. Suitable for dimensional lumber, engineered lumber, and heavy timber framing applications.

Installation Notes

Licensed contractors and experienced carpenters typically install lag bolts on structural assemblies governed by the IRC or IBC. Always drill a properly sized pilot hole and shank clearance hole before driving to prevent wood splitting and ensure full thread engagement. Drive with a socket wrench or impact driver set to a controlled torque to avoid stripping the wood fiber. Zinc-plated lag bolts are not rated for ground contact or pressure-treated lumber exposed to high-moisture conditions — consult applicable code for corrosion-resistance requirements in those applications.
