Description

The Simpson Strong-Drive® WSVF SUBFLOOR Screw is engineered to provide superior performance in subfloor applications, featuring a deep 6-lobed recessed ribbed head that ensures clean countersinking and enhanced bit retention to minimize cam-outs. This innovative screw, with its dual evaluation per ICC-ES AC233 and ICC-ES AC120 standards, is ideal for fastening wood-frame subfloors while allowing easy backing out for future access to floor cavities. The included 6-lobe T25 drive bit makes installation efficient, while the redesigned tip and thread pattern not only facilitates easy starts but also decreases installation torque by up to 25%, resulting in faster driving times. With a gray Quik Guard® coating that is approved for use with fire-retardant treated lumber, these screws provide exceptional holding power that effectively reduces gaps between joists and subfloors, helping to eliminate floor squeaks and enhance overall structural integrity.
