Product Description
The Simpson Strong-Tie Strong-Drive WSV SUBFLOOR Screw (WSV3S) is a collated, #9 x 3-inch structural fastener engineered and extensively tested to efficiently meet demanding wood subfloor applications. Developed specifically for fastening subfloor sheathing using the Quik Drive auto-feed screw driving system, this screw has been re-engineered from the ground up to reduce driving force and increase installation speed - saving time and money on every job. The redesigned tip and variable thread pattern deliver up to 25% less torque while driving and up to 20% faster installation compared to previous designs, all while reducing wear on your tools. With its exceptional holding power, the WSV screw minimizes the gaps between joist and subfloor that are the leading cause of floor squeaks, and screws can be easily backed out when future access to floor cavities is needed. Dual-evaluated under ICC-ES AC233 and AC120 for wood-frame subfloor fastening and finished with a yellow zinc coating applied in accordance with ASTM F1941, the WSV3S delivers professional-grade performance and compliance in every collated strip. This package includes 1,000 screws plus a 6-lobe T25 drive bit.
Key Features
- Up to 25% Less Driving Torque & 20% Faster Installation: Redesigned tip and thread pattern provides easy starts and significantly reduced driving resistance for quicker, more efficient fastening.
- Reduced Tool Wear: Lower installation torque translates directly to less wear on your screw-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.
- Eliminates Floor Squeaks: The superior holding power of WSV screws reduces the gaps between the joist and subfloor that cause floor squeaks.
- Easily Removable: WSV screws can be easily backed out, allowing for future access to floor cavities without damaging the subfloor.
- Dual ICC-ES Evaluated: Evaluated under both ICC-ES AC233 and AC120 for wood-frame subfloor fastening - supporting compliance documentation on permitted projects.
- ASTM F1941 Yellow Zinc Coating: Yellow zinc coating applied in accordance with ASTM F1941 for corrosion resistance and product identification.
- Curved Collation: Collated in a curved strip format compatible with the Quik Drive PRO300S auto-feed screw driving system for fast, continuous fastening.
- Variable Thread Design: Engineered thread geometry optimizes pull-through resistance and pull-out strength in subfloor sheathing applications.
- T25 Drive Bit Included: Each package includes a 6-lobe T25 drive bit (model BITX25) to get you started immediately.
