Simpson Deck-Drive DCU Composite Screw, #10 x 2-3/4 in., Type 316 Stainless Steel, Red Cap Head, Collated 1000-Pack is engineered by Simpson to deliver beautiful, consistent fastening results across all types of composite and PVC decking. Built from Type 316 stainless steel for severe-level corrosion resistance and featuring a color-matched red painted cap head, this collated screw is designed to eliminate the need to mix and match fasteners across different composite decking products - making it a reliable, go-to choice for composite deck installations of every scale.

Key Features

• Tri-lobe thread design - reduces damage to the composite board while driving, preserving the integrity and appearance of the decking surface
• Inverted upper threads - clear excess material during installation to ensure the screw is seated properly and consistently, resulting in a flush, professional finish every time
• Type-17 point - penetrates composite decking with ease for faster starts, reducing installation time and driver bit wear
• Cap head design - prevents mushrooming and material from rising up above the deck surface, delivering a smoother, cleaner look without additional finishing work
• Trex-approved fastener - meets Trex composite decking installation requirements, giving installers confidence the screw is sanctioned for use with one of the most widely used composite decking brands
• T20 6-lobe drive with included driver bit - provides a secure, slip-resistant drive connection, and the included bit means you can get started right away (replacement bit model BITTX20-PL-RC3)
• Type 316 stainless steel construction - provides severe-level corrosion resistance for demanding outdoor environments where moisture and weather exposure are ongoing concerns
• Curved collation format - compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system or attachment, enabling high-speed, high-volume installation without hand-loading individual fasteners
• Red color-matched painted head - blends with popular composite decking colors for a more concealed, finished appearance that complements the deck surface rather than standing out against it

Why This Product

• One screw for all composite decking types - the Deck-Drive DCU is engineered to work across composite and PVC decking applications, eliminating the frustration and job-site confusion of managing multiple fastener types for different board brands or materials
• Severe-level corrosion resistance built in - Type 316 stainless steel construction makes these screws a dependable long-term choice for exterior deck installations exposed to moisture, coastal air, and harsh outdoor conditions
• Cleaner results with less rework - the combination of the cap head design, inverted upper threads, and tri-lobe thread geometry works together to seat each screw flush and consistently, reducing surface damage and the need for touch-ups after installation
• Built for production-speed installation - curved collation makes these screws fully compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system, allowing crews to drive fasteners quickly and efficiently across large deck surfaces without sacrificing placement accuracy or finish quality
