Quik Drive Strong-Drive WSV Subfloor Screws #9 x 1-3/4 in Yellow Zinc (1,000 ct)

The QUIK DRIVE BY SIMPSON STRONG TIE Strong-Drive WSV Subfloor #9 x 1-3/4-in Yellow Zinc Interior Construction Screws are specifically engineered for fastening subfloor sheathing using auto-feed screw driving systems like the Quik Drive® PRO200S, PRO250G2, and PRO300S. These collated screws are designed to reduce installation time and effort while improving floor performance by minimizing squeaks. Key features include a redesigned tip and thread pattern that requires up to 25% less driving torque, enabling up to 20% faster installation. The 6-lobed T25 drive (recessed ribbed head) ensures secure bit retention, reducing cam-outs and allowing clean countersinking. Their high holding power reduces gaps between joists and subfloor, significantly decreasing floor squeaks. These screws are made from carbon steel with a yellow zinc chromate coating for corrosion resistance in dry indoor environments and are suitable for interior wood construction and subfloor applications.
