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 during 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 percent lower driving torque and 20 percent 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.
