DCU234SRD01 Simpson Strong-Tie 2-3/4" DCU Deck-Drive Collated Composite Screw Red 01 1000-CT Carton

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.

The 2 3/8'' Deck-Drive DCU Composite screws are ideal for installing decking products to wooden roof sleeper assemblies and cladding to wood framing. The 2 3/8'' lengths are only available collated for Quik Drive® auto-feed screw driving systems.
