Product Description

The Simpson Deck-Drive DCU Composite Screw (Collated) - #10 x 2-3/4 in., Type 316 Stainless Steel, Gray 01 is engineered to deliver beautiful, professional fastening results across all types of composite and PVC decking. Featuring a color-matched Gray 01 painted cap head designed to blend with popular decking manufacturers, this collated screw combines a clean concealed finish with severe-level corrosion resistance - making it a reliable, go-to fastener for any composite deck installation. The curved collation format is compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system for faster, more consistent drives across the entire deck surface.

Key Features

  • Tri-lobe thread design - reduces stress and damage to the composite board during driving, protecting the integrity and appearance of the decking material
  • Inverted upper threads - clear excess material away from the surface as the screw seats, ensuring a consistently flush, clean finish every time
  • Type-17 point - penetrates composite decking with ease for faster starts, reducing drive time and effort on the job
  • Cap head design - prevents mushrooming and material from rising above the deck surface, resulting in a smooth, professional-looking installation
  • Type 316 stainless steel construction - provides severe-level corrosion resistance, keeping fasteners strong and presentable in outdoor environments exposed to moisture and the elements
  • Gray 01 color-matched painted head - blends with popular composite decking products for a more concealed, finished appearance that complements the deck surface
  • Trex-approved fastener - meets Trex composite decking approval requirements, giving contractors and homeowners confidence when building Trex deck systems
  • T20 6-lobe drive with included driver bit - provides positive bit engagement and reduces cam-out during installation, with a replacement bit available (model BITTX20-PL-RC3)
  • Curved collation format - compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system, enabling high-volume installation with consistent screw placement and reduced fatigue

Why This Product

  • One screw for all composite decking types - the Deck-Drive DCU eliminates the need to mix and match fasteners for different composite or PVC decking products, simplifying material planning and reducing the risk of using the wrong screw on the job
  • Built for a clean, finished look - the cap head combined with inverted upper threads and a color-matched Gray 01 painted head work together to prevent material rise and create a smooth, concealed finish that enhances the overall appearance of the completed deck
  • Severe-level corrosion resistance for outdoor longevity - Type 316 stainless steel construction stands up to harsh outdoor exposure, making these screws a dependable long-term fastening solution for decks subject to moisture, humidity, and coastal conditions
  • Auto-feed system compatibility for faster installation - the curved collation design works with the Simpson Strong-Tie Quik Drive PRO300SG2, allowing contractors to drive screws quickly and consistently across large deck surfaces with less manual effort
