The Simpson Strong-Tie Strong Drive® WSTNL212S #8 x 2-1/2" Screws are ideal for screwing wood-to-wood when their is little concern about corrosion of the fasteners. The most common use of these screws is for subfloor applications because the screw creates a very tight connection between the plywood and joist. Using a Quik Drive® Automatic Tool with a 20" extension saves time and labor thus saving you money.
