Lag Screw

These steel screws have corrosion-resistant finishes. Also known as lag screws, wood screws or lag bolts , they have a hex head for a secure grip with a wrench. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Length is measured from under the head.

Generally supplied in carbon steel with zinc-plated, these screws provide adequate corrosion and oxidation resistance but can tarnish if used extensively. These screw can be finished in a number of anti-corrosive finishes, or even in a different material altogether. Zinc-plated steel screws resist corrosion in wet environments. Hot-dipped galvanized steel screws have a thick coating for better corrosion resistance than zinc-plated steel screws. They’re a good choice for ACQ-treated (arsenic-free) lumber.
