The Type 316 stainless-steel Deck-Drive DCU Composite screw provides severe-level corrosion resistance for all types of composite and PVC decking, and is especially suited for applications in environments with chlorides. The DCU penetrates composite decking with a Type-17 point and is engineered with inverted upper threads that clear excess material to ensure a clean, secure installation. The color-matching painted heads blend with popular manufacturers’ decking for a more concealed, professional finish.
