Strong-Drive WSVF subfloor screw
Simpson Strong-Tie has introduced the Strong-Drive WSVF subfloor screw approved for use with fire-retardant-treated lumber.
The WSVF joins the WSV family of collated screws developed for fastening subfloor sheathing using the Quik Drive auto-feed screw driving system.
Featuring a fire-retardant coating, the WSVF provides corrosion resistance for use with fire-retardant-treated wood and wood-based materials that might otherwise compromise the performance of carbon-steel fasteners.
Thousands of structures have been destroyed by wildfires in California, Oregon, Washington, Colorado, and other states over the past five years. The WSVF provides a no-squeak, efficient subfloor connector for repair and replacement projects opting for fire-resistant subfloor materials.
Like other fasteners in the WSV line, the WSVF also features a redesigned tip and thread pattern to provide easy starts, up to 25% lower driving torque, and 20% faster overall driving. And less installation torque means less wear on tools.
Additional features of the WSV line of fasteners include:
- A 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 incidence of gaps between the joist and subfloor that cause floor squeaks.
- WSV screws can be easily backed out, allowing for easy future access to floor cavities.
