Simpson Strong Deck-Drive™ DCU COMPOSITE Screw

The Deck-Drive DCU Composite screw is engineered to provide beautiful fastening results for all types of composite decking while also offering greater ease of installation, a clean finish and superb corrosion resistance. The Deck-Drive DCU is the go-to-screw for all your composite decking applications, eliminating the need to mix and match screws to the decking.

Deck-Drive DCU Composite decking screws are available in carbon steel with our Quik Guard® coating. For superior corrosion resistance in marine or high-exposure environments, choose the appropriate stainless-steel DCU screw (Type 305 or Type 316). DCU screws provide a clean finish because of their special head design and are available in a wide range of colors, matched to blend with most major decking manufacturers. These are bulk screws, also available collated for the Quik Drive® auto-feed screw driving system.

The 2" Deck-Drive DCU Composite screws are designed to be the fastener of choice for PVC and composite decking, trim and cladding, including composite decking and cladding products, wood/plastic composites, encapsulated wood/plastic composites and HDPE (high-density polyethylene). In addition, the DCU SS screw is the ideal solution for PVC decking.
