Product Description
The Simpson Strong-Tie Strong-Drive WSV Subfloor Screw (Model HCKWSV134S) is a collated #9 x 1-3/4 in. fastener engineered specifically for fastening subfloor sheathing using the Quik Drive auto-feed screw driving system. Re-engineered from the ground up, this screw 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 - keeping your crew moving and your tools in better shape. The deep 6-lobed recessed ribbed head countersinks cleanly and holds the T25 bit securely to eliminate frustrating cam-outs. The exceptional holding power of the WSV screw minimizes gaps between joists and subfloor sheathing, directly targeting the root cause of floor squeaks. Dual-evaluated under ICC-ES AC233 and AC120 for wood-frame subfloor fastening, these screws arrive in a 1,000-count collated pack with a yellow-zinc coating applied in accordance with ASTM F1941. A T25 drive bit (model BITX25) is included.
Key Features
- Up to 25% Less Driving Torque: Redesigned tip and thread pattern provides easy starts and significantly reduced driving force - enabling up to 20% faster driving speeds.
- Reduced Tool Wear: Lower installation torque translates directly into less wear on your auto-feed driving tools, extending tool life on the job.
- Deep 6-Lobed Recessed Ribbed Head: Provides clean countersinking and more secure bit retention for fewer cam-outs during high-volume installation.
- Squeak-Fighting Holding Power: The holding power of WSV screws reduces 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 without destructive removal.
- Dual ICC-ES Evaluation: Evaluated under both ICC-ES AC233 and AC120 for wood-frame subfloor fastening - supporting code-compliant installations.
- ASTM F1941 Yellow-Zinc Coating: Yellow zinc coating applied in accordance with ASTM F1941 for consistent, quality corrosion resistance.
- Variable Thread Design: High-low threaded point and variable thread pattern work together for smooth, efficient driving with superior holding power.
- Collated for Auto-Feed Systems: Curved collation format designed to work seamlessly with compatible Quik Drive auto-feed screw driving systems and attachments.
- T25 Drive Bit Included: Each 1,000-count pack includes one T25 6-lobe drive bit (model BITX25).

Frequently Asked Questions
- What 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, or Project Pro auto-feed screw driving systems and their compatible attachments. A T25 drive bit (model BITX25) is included with each 1,000-count pack.
- Are these screws approved for structural subfloor fastening applications?
- Yes. The WSV Subfloor Screw is dual-evaluated under ICC-ES AC233 and AC120 for wood-frame subfloor fastening, providing code-recognized approval for structural subfloor sheathing applications.
- How do these screws help prevent floor squeaks?
- The holding power of the WSV screw minimizes gaps between the joist and subfloor sheathing, directly addressing the root cause of floor squeaks. Additionally, the screws can be easily backed out if future access to floor cavities is needed.
- What 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 coating is what gives the screws their distinctive yellow appearance and provides a standardized level of corrosion resistance.
