Deck-Drive™ DCU Screw Plug Solution 

The Deck-Drive DCU screw plug solution is a complete hidden deck-fastening system designed for use with our premium DCU Composite screws, and is composed of DCU screw plugs and the auto-set driver bit (each sold separately). The DCU screw plugs are made from materials by major composite and PVC board manufacturers to match your deck and trim boards. No more visible screw heads — a clean, professional finish. Fully compatible with hand-drive and Quik Drive® autofeed screw driving system installations.
