The Simpson Deck-Drive DCU Composite Screw, #10 x 2-3/4 in., Collated, Quik Guard Gray, 1,000-count is engineered by Simpson to deliver professional fastening results across all types of composite and PVC decking. Designed as a true universal composite decking screw, it eliminates the need to mix and match fasteners for different decking products - streamlining procurement and installation on any job. The gray, color-matching cap head blends with popular composite decking boards for a clean, concealed finish, while the curved-collated format pairs with the Simpson Quik Drive PRO300SG2 auto-feed system for high-speed, consistent driving on large-scale deck installations.

Key Features

• Tri-Lobe Thread Design - minimizes stress and damage to the composite board during driving, protecting the deck surface for a cleaner result
• Inverted Upper Threads - clear excess material away as the screw seats, ensuring every fastener sits flush and consistently without leaving raised material around the head
• Type-17 Point - penetrates composite decking quickly for faster starts, reducing installation time on each board
• Cap Head Design - prevents mushrooming and material from rising above the deck surface, producing a smooth, professional-looking finish without additional cleanup
• Quik Guard Coating - provides corrosion resistance equivalent to hot-dip galvanization (ASTM A153, Class D) in some exposures and is approved for use in pressure-treated lumber, giving the installation long-term durability in demanding outdoor environments
• Gray Color-Matching Head - blends with popular composite decking boards for a more concealed, finished appearance that complements the deck rather than drawing attention to fasteners
• Trex-Approved Fastener - meets Trex composite decking requirements, giving builders and contractors confidence when working on Trex deck projects
• Curved Collation Format with T20 6-Lobe Drive - compatible with the Simpson Quik Drive PRO300SG2 auto-feed system and includes a T20 6-lobe driver bit, so crews can begin driving immediately without hunting for additional accessories
