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.

• Redesigned tip and thread pattern provides easy starts and up to 25% less torque while driving - makes for up to 20% faster driving
• Less installation torque also means less wear on tools and more screws driven per battery charge
• Deep 6-lobe recessed ribbed head provides clean countersinking and more secure bit retention for fewer cam-outs
• The holding power of WSV screws reduces the gaps between the joist and subfloor that cause floor squeaks
• WSV screws can be easily backed out, allowing for future access to floor cavities
• 6-lobe T25 drive bit (replacement bit BITTX25)
