For fastening subfloor to wood, decking, underlayment, and backerboard, this corded screwdriver has expanded depth settings for high-density flooring materials. It features reversible and replaceable non-skid teeth and a sure-grip guide tube that increases stability for a broad range of screws. The patented curved collation strips hold the screws up and away from the work surface, making moving and positioning the tool easier. They are also pointed on the inserted end to simplify loading.
