Strong-Drive® WSV SUBFLOOR Screw (Collated)

Strong-Drive® WSV SUBFLOOR Screw

On This Page

Simpson Strong-Tie has re-engineered its popular subfloor screw to reduce driving force and increase installation speed. The new Strong-Drive WSV Subfloor screw has been developed for fastening subfloor sheathing using the Quik Drive® auto-feed screw driving system.

Key Features

  • Redesigned tip and thread pattern provides easy starts and up to 25% less torque while driving1 — makes for up to 20% faster driving2
  • Less installation torque also means less wear on tools
  • Deep 6-lobed 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 T-25 drive bit (replacement bit BITX25)

1. Test data shows the Strong-Drive WSV Subfloor screw requires up to 25% less driving torque in single-material LVL.
2. Test data indicates the redesigned WSV thread pattern will result in 20% faster screw installations.
