Product Description
The Simpson Strong-Tie Strong-Drive WSV212S WSV Subfloor Screw is a collated, #9 x 2-1/2-inch, T25 6-Lobe, Yellow-Zinc coated structural fastener engineered specifically for fastening subfloor sheathing using the Quik Drive auto-feed screw driving system. Simpson Strong-Tie has re-engineered this popular subfloor screw to reduce driving force and increase installation speed - delivering up to 25% less torque and up to 20% faster driving compared to previous designs. The result is a high-performance fastener that reduces floor squeaks, extends tool life, and keeps subfloor installations on schedule. This value pack includes 1,500 collated screws plus a 6-lobe T25 drive bit (model BITX25), and is dual-evaluated under ICC-ES AC233 and 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 significantly reduced drive force for faster, more efficient installation.
- Extended tool life: Less installation torque means less wear on tools over the course of a job.
- Deep 6-lobed recessed ribbed head: Provides clean countersinking and more secure bit retention for fewer cam-outs during driving.
- Squeak-reducing holding power: The holding power of WSV screws reduces the gaps between the joist and subfloor that cause floor squeaks.
- Removable & reversible: WSV screws can be easily backed out, allowing for future access to floor cavities.
- T25 drive bit included: Each pack includes a 6-lobe T25 drive bit (model BITX25) for immediate use.
- Dual code evaluation: Evaluated under ICC-ES AC233 and AC120 for wood-frame subfloor fastening applications.
- ASTM-compliant finish: Yellow zinc coatings are applied in accordance with ASTM F1941.
- 1,500-count collated pack: High-volume collated format designed for use with the Quik Drive auto-feed screw driving system.

Frequently Asked Questions
- What auto-feed screw driving systems are compatible with these collated subfloor screws?
- The WSV212S screws are designed to install with the Simpson Strong-Tie Quik Drive PRO250G2, PRO300S, and Project Pro auto-feed screw driving systems and their compatible attachments. Each 1,500-count pack also includes a 6-lobe T25 drive bit (model BITX25) for use with these systems.
- Are these screws evaluated or certified for structural subfloor applications?
- Yes. The WSV212S screws are dual-evaluated under ICC-ES AC233 and AC120 for wood-frame subfloor fastening, making them suitable for structural subfloor sheathing applications that require code-recognized fasteners.
- How do these screws help prevent floor squeaks?
- The holding power of the WSV screw design reduces the gaps that can develop between the joist and subfloor - gaps that are a primary cause of floor squeaks. Additionally, the screws can be easily backed out if future access to floor cavities is needed, without damaging the surrounding material.
- What design improvements help reduce driving force and speed up installation?
- The WSV212S features a redesigned tip and variable thread pattern that provides easy starts and delivers up to 25% less torque while driving, resulting in up to 20% faster installation compared to previous designs. The deep 6-lobed recessed ribbed head also provides more secure bit retention, reducing cam-outs, and the reduced torque means less wear on tools over the course of a job.
