Hillman Fasteners 230045 Hex Head Lag Bolt 5/16x1-1/2 Zinc 100pk

Product Description

The HILLMAN FASTENERS 230045 is a zinc-plated hex head lag bolt supplied in a 100-piece pack. Lag bolts are heavy-duty wood screws with a hex drive head, used to fasten structural members, hardware, and fixtures to wood substrate. The 5/16-inch diameter by 1-1/2-inch length profile suits lighter-duty structural connections where a through-bolt is not practical. The zinc plating provides baseline corrosion resistance for interior and protected exterior applications. Installation requires a socket wrench or nut driver rather than a screwdriver, delivering high clamping force directly into wood.

This lag bolt is commonly used in residential and light commercial construction, framing, decking, fence assembly, equipment mounting, and general carpentry. The 100-piece pack format suits contractors and tradespeople who install fasteners in volume. Carpenters, general contractors, and maintenance technicians are the typical installers for this fastener type.

Installation Notes

Lag bolts should be installed by a qualified carpenter or contractor following applicable building codes. Always drill a pilot hole sized to the shank diameter before driving to prevent wood splitting and reduce the risk of fastener shear. Use a properly rated socket wrench or impact driver set to a controlled torque to avoid stripping the hex head. Confirm that the base material and connection type meet the load requirements specified by the project engineer or local building authority.
