The Simpson Strong-Tie Deck-Drive DCU Composite Screw is engineered for strength, clean finishes, and reliable fastening in composite and PVC decking projects. Featuring a cap head that prevents mushrooming, these screws ensure smooth, professional results across a wide range of composite decking brands. Made of 316 Stainless Steel with a Quik Guard coating the DCU provides lasting corrosion resistance in everything from standard residential decks to harsh coastal environments.
