Subfloor screw shows off fire-retardant coating

From: Simpson Strong-Tie

Simpson Strong-Tie presents the Strong-Drive WSVF subfloor screw, approved for use with fire-retardant-treated lumber. WSVF joins the WSV family of collated screws, which has been developed for fastening subfloor sheathing using the Quik Drive auto-feed screw driving system. Featuring a fire-retardant coating, the subfloor screw provides corrosion resistance for use with fire-retardant-treated wood and wood-based materials that might otherwise compromise the performance of carbon-steel fasteners. WSVF offers a no-squeak, efficient subfloor connector for repair and replacement projects that opt for fire-resistant subfloor materials.
