Smart-Bit Deck Screw Depth Setter is designed to make fastening decks， drywall， and general screw setting easier and faster， with clean and uniform results: perfectly set screws every time. The tool is adjustable so that it can be used with many different screw types and sizes， and features an Auto-Stop mechanism that sets the screw at the target 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.
