Simpson Strong-Tie Strong-Drive No. 9 X 2 in. L T25 Yellow Zinc WSV Subfloor Screws 1 pk

Simpson Strong-Tie has re-engineered its popular subfloor screw to reduce driving force and increase installation speed. The new 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 and AC120 for wood-frame subfloor fastening. 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.
