The Simpson Deck-Drive DCU Composite Screw, #10 x 2-3/4 in., Collated, Quik Guard Red 01, T20, 1000-Pack is a purpose-engineered collated fastener built specifically for composite and PVC decking applications. Designed by Simpson to eliminate the need to mix and match screws across different decking products, the DCU delivers a clean, professional finish on every installation - combining a color-matched Red 01 cap head, a tri-lobe thread design, and Quik Guard corrosion protection into a single go-to solution for composite deck boards. The curved collation format and compatibility with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system make large-scale deck installations faster and more consistent from start to finish.

Key Features

• Tri-lobe thread design - reduces stress and damage to the composite board during driving, preserving the integrity of the decking surface throughout installation
• Inverted upper threads - clear excess material away from the screw head so every fastener seats properly and consistently, eliminating raised or uneven results
• Type-17 point - penetrates composite decking with ease for faster starts, reducing drive time and installation effort across the entire deck
• Cap head design - prevents mushrooming and material from rising above the deck surface, producing a smooth, clean-looking finish that requires no additional correction
• Quik Guard coating - provides corrosion resistance equivalent to hot-dip galvanization (ASTM A153, Class D) in some exposures and is suitable for use in pressure-treated lumber, making it a dependable choice for outdoor decking environments
• Red 01 color-matched head - blends with popular composite decking colors for a more concealed, finished appearance that elevates the overall look of the deck
• Trex-approved fastener - meets Trex's requirements for use with Trex composite decking, giving contractors and homeowners added confidence in code and warranty compliance
• T20 6-lobe drive with included driver bit - provides positive bit engagement and reduces cam-out, while the included bit means you can begin work immediately without sourcing additional accessories
• Curved collation format - compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system, enabling rapid, repetitive fastening that significantly increases productivity on larger decking projects

Why This Product

• One screw for all composite decking types - the Deck-Drive DCU is engineered to work across all types of composite and PVC decking, so contractors can standardize on a single fastener rather than managing multiple screw specifications for different board brands or product lines
• Concealed, professional finish built into the design - the cap head and color-matched Red 01 painted head work together to prevent surface mushrooming and blend the fastener into the deck board, delivering an aesthetically clean result without extra finishing steps
• Outdoor-grade corrosion resistance backed by a recognized standard - the Quik Guard coating meets a corrosion resistance level equivalent to hot-dip galvanization (ASTM A153, Class D) in some exposures, providing long-term protection suited to the demands of exposed outdoor deck installations and pressure-treated substructures
• Engineered for high-volume installation speed - the combination of a Type-17 point for fast starts, curved collation, and compatibility with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system allows crews to drive screws quickly and consistently, reducing labor time on full deck builds
