Collated Screws, Simpson Strong-Tie, Strong-Drive, #9 Thread, 2-1/2 in L, Rimmed Flat Head, Zinc Plated, 750-pk

The Strong-Drive WSV Subfloor screw is the only fastener to be dual-evaluated under ICC-ES AC233 and AC120 for wood-frame subfloor fastening. 2 in WSV Subfloor screws are recommended for Advantech® flooring and sheathing products. Fastening with WSV Subfloor screws provides excellent holding power and combining the WSV Subfloor screw with adhesives can provide the ultimate subfloor solution. This testing indicates that the WSV Subfloor screws have lateral, shear and withdrawal values that exceed those of 10d common nails and diaphragms built with WSV Subfloor screws meet or exceed the strength and stiffness of wood frame diaphragms built with 10d nails.

• Redesigned tip and thread pattern provides easy starts and up to 25% less torque while driving - makes for up to 20% faster driving
• Less installation torque also means less wear on tools and more screws driven per battery charge
• Deep 6-lobe recessed ribbed head provides clean countersinking and more secure bit retention for fewer cam-outs
• The holding power of WSV screws reduces the gaps between the joist and subfloor that cause floor squeaks
• WSV screws can be easily backed out, allowing for future access to floor cavities
• 6-lobe T25 drive bit (replacement bit BITTX25)
• Dual-evaluated under ICC-ES AC233 and AC120 for wood-frame subfloor fastening
• Yellow zinc coatings are applied in accordance with ASTM F1941
