#9 x 3″ Simpson HCKWSV3S WSV Subfloor Screw – Yellow Zinc, Pkg 500

The Simpson Strong-Drive WSV Subfloor Screw is purpose-built for fast, secure subfloor installations. Designed specifically for use with Simpsons Quik Drive auto-feed systems, these collated screws dramatically speed up floor assembly while reducing squeaks, callbacks, and crew fatigue.

Engineered with a ribbed head for clean countersinking and a redesigned thread pattern for aggressive pull-down power, WSV screws set the standard for structural fastening in subfloor, sheathing, and decking projects.
