Product Description
The Simpson Strong-Drive WSV Subfloor Screw is a collated structural fastener engineered specifically for fastening subfloor sheathing to wood framing using the Quik Drive auto-feed screw driving system. Developed by Simpson Strong-Tie and extensively tested for demanding wood-frame applications, this #9 x 2 in. screw has been re-engineered with a redesigned tip and variable thread pattern to reduce driving force and increase installation speed compared to its predecessor - delivering faster, cleaner results with less wear on your tools and equipment.
Key Features
- Redesigned tip and thread pattern provides easy starts and up to 25% less torque while driving - reduces operator fatigue and speeds up installation by up to 20%, helping crews cover more subfloor in less time
- Reduced installation torque - puts less strain on auto-feed driving systems and bits, extending tool life and lowering overall equipment wear costs
- Deep 6-lobed recessed ribbed head provides clean countersinking and more secure bit retention - minimizes cam-outs for a cleaner finished surface and fewer interruptions during high-volume installation
- High holding power reduces gaps between joist and subfloor - directly addresses the root cause of floor squeaks, keeping subfloor assemblies tight and quiet over time
- WSV screws can be easily backed out - allows future access to floor cavities without damaging surrounding material, a practical advantage for renovation and inspection work
- T25 6-lobe drive bit included - crews have everything needed to get started right out of the pack, with no separate bit purchase required
- Dual-evaluated under ICC-ES AC233 and AC120 for wood-frame subfloor fastening - provides the code-compliance documentation professionals need for inspections and permitted work
- Yellow zinc coating applied in accordance with ASTM F1941 - ensures a consistent, standardized finish that meets established industry corrosion-protection requirements
Why This Product
- Engineered to eliminate floor squeaks at the source - the variable thread design, high-low threaded point, and strong holding power work together to close the gap between joist and subfloor, keeping the assembly tight long after installation is complete
- Built for speed without sacrificing performance - the re-engineered tip and thread pattern deliver up to 25% less driving torque and up to 20% faster installation, making this screw a smart choice for any subfloor project where time on the job matters
- Code-evaluated and professionally trusted - dual evaluation under ICC-ES AC233 and AC120 means this fastener meets recognized standards for wood-frame subfloor fastening, supporting smooth inspections on permitted residential and commercial builds
- Designed to work seamlessly with Quik Drive auto-feed systems - curved collation and compatibility with the Simpson Strong-Tie Quik Drive PRO200S, PRO250G2, PRO300S, and Project Pro systems means this screw integrates directly into professional auto-feed workflows with minimal setup

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.
