Description
The Simpson Strong-Tie Deck-Drive™ DCU Composite Screw is designed for composite and PVC decking, trim, and cladding where strength, clean finishes, and durability are a must. Featuring a cap head that prevents mushrooming, these screws ensure a smooth, professional look across all major composite brands. The Quik Guard®–coated 316 stainless steel offers dependable corrosion resistance for everything from residential decks to high-exposure and marine environments.
Built for efficiency, the DCU screw features a tri-lobe thread design and unique cut point that penetrate dense composites with ease while minimizing board damage.
