Low Carbon Hex Head Lag Screws – Plain Finish: Reliable Fastening for Everyday Structural Wood Applications

Low carbon hex head lag screws with a plain finish are a time-tested, cost-effective solution for wood-to-wood and wood-to-masonry fastening where strength, simplicity, and reliability are essential. Made from low carbon steel, these lag screws are ideal for non-corrosive indoor applications such as framing, furniture building, cabinetry, and general carpentry projects.

These screws feature a hexagonal head, designed to be driven with a wrench or socket for maximum torque. The coarse threads provide superior grip in wood, allowing the screw to draw materials tightly together for a strong, lasting connection. Their plain (uncoated) finish makes them best suited for dry, interior environments where moisture and corrosion are not a concern.

What sets low carbon lag screws apart is their versatility and ease of use. While they require pre-drilled pilot holes to prevent wood splitting, they deliver strong, stable joints in everything from structural framing to ledger boards and heavy-duty shelving.
