The SDWS Exterior Wood Structural Screw by Simpson is designed to install easily and provide superior strength when compared to traditional through bolting or lag screws. These structural wood screws are ideal for both contractors and the do-it-yourselfer.

This screw offers a bold thread design that provides exceptional holding power, along with the patented 4CUT tip that ensures fast starts, cutting down on installation torque and eliminating the need for pre-drilling in most applications. Under-head nibs that offer outstanding control when seating the large washer head that provides the ultimate in bearing area.

Double-barrier coating provides corrosion resistance equivalent to hot-dip galvanization.
