Lag Screw

Lag Screw

These steel screws have corrosion-resistant finishes. Also known as lag 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.

• 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.

• Custom Sizes – Our unique mass customization manufacturing operation allows us to customize sizes far more easily than any other provider.

Application

Lag screws are used to lag together lumber framing, to lag machinery feet to wood floors, and for other heavy carpentry applications.
