Product Description
The Simpson Strong-Tie Strong-Drive WSV Subfloor Screw (Model WSV134S) is a collated #9 x 1-3/4 in. subfloor 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 - saving time, reducing operator fatigue, and extending tool life. Its deep 6-lobed recessed ribbed head countersinks cleanly and holds the drive bit securely, virtually eliminating cam-outs. With exceptional holding power that minimizes gaps between the joist and subfloor, WSV screws help prevent the floor squeaks that plague lesser fastening methods. 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, this 2,000-piece pack delivers professional-grade performance on every installation. A T-25 6-lobe drive bit is included.
