The Simpson Deck-Drive DCU Composite Screw (Collated) - #10 x 2-3/4 in., Quik Guard Gray 01 is engineered by Simpson for composite and PVC decking installations where a clean, professional result matters. Designed as a true universal composite decking fastener, it eliminates the guesswork of matching screws to specific decking products - including serving as an approved fastener for Trex composite decking. The curved-collated format pairs with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system for faster, more consistent installation across the full deck surface.

Key Features

• Tri-Lobe Thread Design - reduces damage to the composite board while driving, protecting the surface integrity of your decking investment
• Inverted Upper Threads - clear excess material as the screw seats, ensuring consistent, flush installation without unsightly raised edges
• Type-17 Point - penetrates composite decking with ease for faster starts, reducing drive time and operator fatigue across large deck projects
• Cap Head Profile - prevents mushrooming and material from rising above the deck surface, delivering a smoother, cleaner finished appearance
• Gray 01 Color-Matching Painted Head - blends with popular composite decking colors to provide a more concealed, finished look that enhances curb appeal
• Quik Guard Coating - provides corrosion resistance equivalent to hot-dip galvanization (ASTM A153, Class D) in some exposures, and is compatible with pressure-treated lumber
• T20 6-Lobe Drive - offers positive bit engagement and reduced cam-out, with a driver bit included so you can get started right away
• Curved Collation Format - compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system, enabling hands-free, no-bend driving for significantly faster deck board installation
• Trex-Approved Fastener - meets Trex's approval requirements, giving contractors and homeowners confidence when installing Trex composite decking products

Why This Product

• One screw for every composite deck board - the Deck-Drive DCU is engineered for all types of composite and PVC decking, removing the need to stock or sort multiple screw types for different decking brands or profiles
• Built-in surface protection at the thread level - the combination of tri-lobe threads and inverted upper threads actively minimizes board damage and clears excess material during driving, resulting in a consistently clean, seated finish without touch-up work
• Corrosion resistance rated for demanding environments - Quik Guard coating delivers a level of corrosion resistance equivalent to hot-dip galvanization (ASTM A153, Class D) in some exposures, making these screws a reliable long-term choice for outdoor deck construction involving pressure-treated framing
• System-ready for high-speed installation - the curved-collated design is purpose-built to work with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed driving system, allowing installers to drive screws quickly and accurately without stopping to position each fastener by hand
