Product Description
The Simpson Strong-Tie Strong-Drive WSVF Subfloor Screw (Model WSVF2S) is a re-engineered collated fastener developed specifically for fastening subfloor sheathing using the Quik Drive auto-feed screw driving system. Simpson Strong-Tie has redesigned the tip and thread pattern to reduce driving force by up to 25% and increase installation speed by up to 20%, making this #9 x 2 in. screw one of the most efficient subfloor fasteners available. The superior holding power of the WSVF screw minimizes gaps between the joist and subfloor - directly addressing the root cause of floor squeaks. Packaged in a 2,000-count collated strip, this screw is engineered for high-volume professional subfloor installation. The gray Quik Guard coating is approved for use with Fire Retardant Treated (FRT) lumber per ICC-ES ESR-1472, and the screw is dual-evaluated per ICC-ES AC233 and ICC-ES AC120 for wood-frame subfloor fastening.
Key Features
- Up to 25% less torque & 20% faster driving: Redesigned tip and thread pattern provides easy starts and dramatically reduces driving effort, boosting installation speed.
- Reduced tool wear: Lower installation torque means less wear on driving tools over the course of a project.
- Deep 6-lobed recessed ribbed head: Provides clean countersinking and more secure bit retention for fewer cam-outs.
- Eliminates floor squeaks: The holding power of WSVF screws reduces the gaps between the joist and subfloor that cause floor squeaks.
- Removable for future access: WSVF screws can be easily backed out, allowing for future access to floor cavities.
- FRT lumber approved: Gray Quik Guard coating is approved for use in Fire Retardant Treated Lumber per ICC-ES ESR-1472.
- Dual code evaluation: Evaluated per ICC-ES AC233 and ICC-ES AC120 for wood-frame subfloor fastening.
- Includes T25 drive bit: 6-lobe T25 drive bit (model BITX25) included in the package.
- High-volume collated packaging: Ships in a 2,000-count collated strip for efficient, uninterrupted installation.

Frequently Asked Questions
- What auto-feed screw driving systems are compatible with these collated subfloor screws?
- The WSVF2S screws are designed to install with the Simpson Strong-Tie Quik Drive PRO200S, PRO250G2, PRO300S, or Project Pro auto-feed screw driving systems and their compatible attachments. The curved collation type is specifically suited for use with these systems.
- Can these screws be used with Fire Retardant Treated lumber?
- Yes. The gray Quik Guard coating on the WSVF2S screws is approved for use with Fire Retardant Treated (FRT) lumber per ICC-ES ESR-1472, making them suitable for subfloor applications where FRT lumber is required.
- What certifications do these subfloor screws carry?
- The WSVF2S screws are dual-evaluated per ICC-ES AC233 and ICC-ES AC120 for wood-frame subfloor fastening, providing third-party verification of their performance for structural subfloor applications.
- Can these screws be removed after installation if access to the floor cavity is needed?
- Yes. The WSVF screws are designed to be easily backed out, allowing for future access to floor cavities without damaging the surrounding subfloor material. This makes them a practical choice when periodic access beneath the subfloor may be required.
