WSV Timber Screw Flooring Screw — Quik Drive System

The WSV is the best solution for fixing subfloor, bracing, bottom plate and stair applications. Simpson Strong-Tie has re‑engineered its popular subfloor screw to reduce torque and save time. The WSV screw reduces the gaps between the joist and subfloor that cause floor squeaks due to its superior holding power. 

Key Features
  • The WSV tip and thread pattern provide easy starts and up to 25% less torque — which leads to 20% faster driving
  • Less torque means less wear on tools
  • Head design provides a clean countersink and prevents cam-outs 
  • A combination of the thread and head design gives greater clamping force to eliminate squeaking floors
  • Can be easily backed out, unlike nails
Scope of Use
  • Subfloor, Mid Floor
  • Timber-to-Timber
  • Timber Flooring
Limitations on Use
  • These coated fasteners possess a level of corrosion resistance that makes them suitable for use in some exterior and corrosive environments and with some preservative-treated timber.
  • For applications in higher-exposure applications, consider Type-300 series stainless-steel fasteners for superior corrosion resistance. Bit(s) included with every box of screws.
  • Pre-drilling and countersink may be necessary at ends, butt joints, and on applications where denser material is used. Follow board manufacturers recommendations where applicable.


Statement of Building Code Compliance
  • WSV Timber Screw Flooring Screws are compliant with NZS 3604:2011
