Smart-Bit® DECK Screw Depth Setter for Decks, Drywall and General Use sets fasteners to the desired depth below the work surface, every time. The tool"s AUTO-STOPTM mechanism stops the screw at the set depth without stripping the screw recess. A free spinning stop collar with rubber o-ring protects the work surface from damage or marking. The Depth Setter works with both Phillips® and Torx® bits and is designed for use with Starborn fasteners, although it works well with other fastener products as well.
