Structural Screws

Structural screws are used in many construction tasks. You can use them for framing, decking, and even building kids’ outdoor playgrounds. They also replace bolts and lag screws in a variety of high-tension applications.

Heavy-duty structural applications require sturdy screws that offer strength and stability. They don't require pre-drilled holes or additional parts, such as washers and nuts. This gives them an edge over lags and bolts when it comes to convenience and strength.

These heavy-duty screws are specially designed for framing, ledgers, piers, decking, and other load-bearing applications. They provide maximum holding power and weather resistance.
