The Simpson Deck-Drive DCU Composite Screw, #10 x 2-3/4 in., Type 316 Stainless Steel, Brown 01 (1,000-Qty, Collated) is engineered specifically for composite and PVC decking applications, delivering professional fastening results with greater ease of installation, a clean concealed finish, and severe-level corrosion resistance. Designed as a true universal composite decking fastener, the DCU eliminates the need to mix and match screws across different decking brands and materials - including serving as an approved fastener for Trex composite decking. The curved collated format is compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system, making large-scale deck installations significantly faster and more consistent.

Key Features

• Tri-lobe thread design - reduces stress and damage to composite board material during driving, protecting the deck surface for a cleaner finished result
• Inverted upper threads - clear excess material away as the screw seats, ensuring every fastener is driven consistently flush without raised edges or surface buildup
• Type-17 point - penetrates composite decking quickly for faster starts, reducing installation time and minimizing the effort required on each fastener
• Cap head design - prevents mushrooming and keeps decking material from rising above the surface, producing a smooth, professional-looking finish across the entire deck
• Type 316 stainless steel construction - provides severe-level corrosion resistance, making these screws well-suited for demanding outdoor environments including coastal and high-moisture applications
• Brown 01 color-matching painted head - blends with popular composite decking colors to create a more concealed, aesthetically refined installation
• T20 6-lobe drive with included driver bit - delivers positive bit engagement and reduced cam-out, improving control and speed during installation
• Approved fastener for Trex composite decking - provides verified compatibility and peace of mind when working on Trex deck projects

Why This Product

• One screw for all composite decking types - the Deck-Drive DCU is engineered to work across all composite and PVC decking materials, eliminating the guesswork of matching different fasteners to different boards and simplifying job site inventory
• Purpose-built features protect your decking investment - the combination of tri-lobe threads, inverted upper threads, and a cap head work together to prevent surface damage, inconsistent seating, and mushrooming, resulting in a cleaner and more durable installation
• Severe-level corrosion resistance built in - Type 316 stainless steel construction goes beyond standard outdoor fasteners, offering the durability needed for long-term performance in harsh, moisture-heavy environments where lesser materials would fail prematurely
• Engineered for high-volume, efficient installation - the curved collated format and compatibility with the Simpson Strong-Tie Quik Drive auto-feed system allow crews to drive fasteners rapidly and consistently, reducing labor time on large composite deck projects
