High-Quality Lag Bolts and Lag Screws

What is a Lag Bolt?

A lag bolt (also commonly referred to as a lag screw) is a heavy-duty industrial fastener specifically designed for fastening into wood. Featuring a sturdy hex head and coarse, deeply cut threads, they provide maximum gripping power and pull-out resistance when driven into timber, ensuring a robust and long-lasting structural hold.

Common Construction Applications

Because of their exceptional holding strength, lag screws are heavily relied upon to bear intense loads in heavy lumber and timber assemblies. They are commonly used to secure wooden posts and beams, as well as for various household and commercial construction projects. Common applications include:

• Securing heavy wooden posts, beams, and timber framing
• Attaching wood structures to masonry or concrete (when paired with a lag shield anchor)
• Building outdoor decks, boardwalks, and retaining walls
• General household and commercial heavy wood construction
