Product Description
The Simpson Strong-Tie Strong-Drive WSV Subfloor Screw (Model HCKWSV2S) is a collated, #9 x 2-inch structural fastener engineered specifically for fastening subfloor sheathing using the Quik Drive auto-feed screw driving system. Simpson Strong-Tie structural fasteners are engineered and extensively tested to efficiently meet your most demanding wood and metal applications. The WSV has been re-engineered to reduce driving force and increase installation speed compared to its predecessor, delivering faster, cleaner installations with less wear on your tools. This 1,000-piece yellow zinc-coated pack is dual-evaluated under ICC-ES AC233 and AC120 for wood-frame subfloor fastening, making it a code-compliant choice for professional subfloor assemblies.
Key Features

Frequently Asked Questions
- Which auto-feed screw driving systems are compatible with these collated screws?
- The WSV Subfloor Screw is designed to install with the Simpson Strong-Tie Quik Drive PRO200S, PRO250G2, PRO300S, and Project Pro auto-feed screw driving systems and their compatible attachments. A T25 6-lobe drive bit (model BITX25) is included with this 1,000-piece pack.
- What makes the WSV screw better at preventing floor squeaks?
- The holding power of WSV screws reduces the gaps between the joist and subfloor that are a primary cause of floor squeaks. The variable thread design and high-low threaded point optimize penetration and grip, while the 2/3-threaded shank balances clamping force and pullout resistance to keep the subfloor assembly tight over time.
- Are these screws code-evaluated for subfloor fastening applications?
- Yes. The WSV Subfloor Screw is dual-evaluated under ICC-ES AC233 and AC120 for wood-frame subfloor fastening, making it a code-compliant choice for professional subfloor assemblies.
- What type of coating do these screws have, and what standard does it meet?
- These screws feature a yellow zinc coating applied in accordance with ASTM F1941. The yellow zinc finish provides corrosion resistance suitable for interior subfloor sheathing applications.
