Product Description
The Simpson Strong-Tie Strong-Drive WSVF Subfloor Screw (Model WSVF3S) is a collated, #9 x 3-inch, T25 6-lobe fastener engineered specifically for fastening subfloor sheathing using the Quik Drive auto-feed screw driving system. Re-engineered from the ground up, the WSVF features a redesigned tip and variable thread pattern that delivers up to 25% less driving torque and up to 20% faster installation compared to previous designs - saving time, reducing tool wear, and improving overall productivity on the job site. Protected by a Gray Quik Guard coating and dual-evaluated per ICC-ES AC233 and ICC-ES AC120, this screw is built to meet the most demanding wood-frame subfloor fastening requirements, including use with Fire Retardant Treated (FRT) lumber. Each pack contains 1,000 screws.
Key Features
- Up to 25% less torque & 20% faster driving: Redesigned tip and thread pattern provides easy starts and dramatically reduced driving resistance for quicker, more efficient installation.
- Reduced tool wear: Lower installation torque means less stress on your tools, extending tool life and reducing maintenance costs.
- Deep 6-lobed recessed ribbed head: Provides clean countersinking and more secure bit retention for fewer cam-outs, keeping work moving without interruption.
- Eliminates floor squeaks: The superior holding power of WSVF screws reduces gaps between the joist and subfloor - the primary cause of annoying floor squeaks.
- Reversible installation: WSVF screws can be easily backed out, allowing for future access to floor cavities when needed.
- Gray Quik Guard coating: Approved for use with Fire Retardant Treated (FRT) lumber per ICC-ES ESR-1472.
- Dual code evaluation: Evaluated per both ICC-ES AC233 and ICC-ES AC120 for wood-frame subfloor fastening applications.
- Drive bit included: Comes with a 6-lobe T25 drive bit (model BITX25).
- Collated curved strip: Compatible with the Quik Drive auto-feed system for high-volume, ergonomic installation.

Frequently Asked Questions
- What tool is required to install the WSVF3S subfloor screws?
- These collated screws are designed to install with the Simpson Strong-Tie Quik Drive PRO300S auto-feed screw driving system or compatible Quik Drive attachment. A 6-lobe T25 drive bit (model BITX25) is included with each 1,000-count pack.
- Are these screws approved for use with Fire Retardant Treated lumber?
- Yes. The Gray Quik Guard coating on the WSVF3S is approved for use with Fire Retardant Treated (FRT) lumber per ICC-ES ESR-1472, making these screws a compliant choice for subfloor applications where FRT materials are specified.
- What evaluations or certifications does the WSVF3S carry for subfloor fastening?
- The WSVF3S is dual-evaluated per ICC-ES AC233 and ICC-ES AC120 for wood-frame subfloor fastening, meeting the requirements for structural fastener performance in residential and commercial subfloor applications.
- Can the WSVF3S screws be removed after installation if access to the floor cavity is needed?
- Yes. WSVF screws are designed to be easily backed out, allowing for future access to floor cavities when needed without damaging the surrounding subfloor sheathing.
