For composite or PVC decking. 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 they are suited for.

Available in color-matching painted-head stainless steel. For superior corrosion resistance in marine or high-exposure environments, choose the appropriate stainless-steel DCU Composite screw (Type 316 or Type 305). These DCU Composite screws are now available with color-matching painted heads in 11 colors to blend with popular decking manufacturers, and to provide a more concealed, professional finish.

For medium levels of corrosion resistance, Deck-Drive DCU Composite screws are avalable in 11 colors of Quik Guard® coating — also matched to blend with most major decking manufacturers. These screws are offered in bulk for hand drive applications, and collated for the Quik Drive® auto-feed screw driving system.
