Hillman Fasteners 812024 Galvanized Hex Lag Screw 100 Pack

Product Description

The HILLMAN FASTENERS 812024 is a galvanized hex lag screw designed for heavy-duty fastening in wood construction and outdoor applications. Measuring 1/4 inch in diameter by 5 inches in length, this screw features coarse threads and a hexagonal drive head for high torque installation with a socket wrench or impact driver. The hot-dip galvanized finish provides enhanced corrosion resistance compared to standard steel fasteners, making it suitable for exterior use where moisture and weather exposure are a concern. Each box contains 100 screws, supporting production-rate installation on larger projects.

This lag screw is commonly used in residential and light commercial construction tasks including deck framing, retaining wall assembly, and outdoor play equipment installation. When paired with a lag shield anchor, it can also be used in masonry substrates such as concrete block or brick. Installation requires a pre-drilled pilot hole sized appropriately for the thread diameter to prevent wood splitting and ensure proper seating. These fasteners are well suited for carpenters, framers, deck builders, and general contractors working on structural wood connections.

Installation Notes

Installation should be performed by a qualified carpenter, framer, or tradesperson familiar with structural fastening practices. Always drill a properly sized pilot hole before driving the lag screw to avoid splitting the wood or damaging the fastener threads. The hex head requires clearance above the fastener for socket or wrench engagement. Follow applicable building codes, including IRC structural fastening requirements, when using lag screws in load-bearing or deck framing applications.
