WSV212S Strong-Drive WSV SUBFLOOR Screw (Collated) #9 x 2-1/2 in. T25, Yellow-Zinc (1500-Qty)

Redesigned tip and thread pattern enables easy starts and up to 25% less torque during driving, leading to up to 20% faster installation. Reduced installation torque also results in less wear on tools. The deep 6-lobed recessed ribbed head ensures clean countersinking and more secure bit retention for fewer cam-outs. The holding power of these screws minimizes gaps between the joist and subfloor that cause floor squeaks. These screws can be easily removed, allowing for future access to floor cavities
