The Deck-Drive DSV Wood screw is a powerful fastening solution for preservative-treated decking applications. With its under-head nibs and fast-start tip, the DSV is ideally suited to be driven and countersunk into today’s wood deck boards. The shank is designed to withstand the swelling and shrinkage that is common with fast-growth lumber. Available in hand-drive and in collated strips for use in the Simpson-Strong-Tie Quik Drive auto-feed screw driving system, DSV screws are also offered in a variety of sizes to fasten fascia and trim.
