Smart-Bit(R) 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(R) and Torx(R) bits and is designed for use with Starborn fasteners, although it works well with other fastener products as well.
