Simpson Strong-Tie Strong-Drive #9 x 1-3/4in L T25 Yellow Zinc Interior Wood Screw 2000pk

Simpson Strong-Tie has re-engineered its popular subfloor screw to reduce driving force and increase installation speed. The premium quality Strong-Drive WSV Subfloor screw has been developed for fastening subfloor sheathing using the Quik Drive auto-feed screw driving system. The Strong-Drive WSV Subfloor screw is the only fastener to be dual-evaluated under ICC-ES AC233 & AC120 for wood-frame subfloor fastening. 2 In. WSV Subfloor screws are recommended for Advantech flooring and sheathing products. Fastening with WSV Subfloor screws provides excellent holding power. and combining the WSV Subfloor screw with adhesives can provide the ultimate subfloor solution. This testing indicates that the WSV Subfloor screws have lateral. shear and withdrawal values that exceed those of 10d common nails. and diaphragms built with WSV Subfloor screws meet or exceed the strength and stiffness of wood frame diaphragms built with 10d nails. Use Strong-Drive WSVF Subfloor screw variant for fire-retardant wood-based materials. The Strong-Drive WSVF Subfloor screw is an available variant with a gray Quik Guard coating that is recognized for corrosion resistance in IAPMO UES ER-192 for Exposures 1 & 3 as described in ICC-ES AC257. Like the WSV Subfloor screw. the WSVF Subfloor screws are designed for dry service applications. The coating system on the WSVF screws will provide corrosion resistance for use with wood and wood-based materials in dry service where the wood and wood-based materials have treatment retentions typical of AWPA Use Categories 1-4A and fire-retardant-treated wood and wood-based materials that are recognized in an evaluation report where corrosion effects of the fire-retardant chemical are referenced to code prescribed protection systems for carbon steel fasteners.
