Simpson Strong-Tie Strong-Drive structural fasteners are engineered and extensively tested to efficiently meet your most demanding wood and metal applications. The Strong-Drive family is designed to install easier than other fastening methods, which saves time and money. The WSV Subfloor screw was developed for fastening subfloor sheathing using the Quik Drive auto-feed screw driving system. It has been re-engineered to reduce driving force and increase installation speed.
