The Simpson Deck-Drive DCU Composite Screw, #10 x 2 3/4 in., Collated, Quik Guard Brown 01, T20 is an engineered fastening solution from Simpson designed specifically for composite and PVC decking applications. Its tri-lobe thread profile, inverted upper threads, and cap head geometry work together to deliver a clean, professional finish on every drive, while the curved-collated format and compatibility with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system keep installation fast and consistent across the entire deck surface. Color-matched in Brown 01, these screws blend with popular composite decking to provide a more concealed, attractive result.

Key Features

• Tri-lobe thread design - reduces stress and damage to the composite board during driving, preserving the integrity and appearance of the decking surface
• Inverted upper threads - clear excess material ahead of the head so the screw seats properly and consistently every time, eliminating raised or uneven fastener heads
• Type-17 point - penetrates composite decking with ease for faster starts, reducing the effort and time needed on each fastener
• Cap head design - prevents mushrooming and material from rising above the deck surface, resulting in a smoother, cleaner-looking installation
• Quik Guard coating - provides corrosion resistance equivalent to hot-dip galvanization (ASTM A153, Class D) in some exposures, making these screws suitable for use in pressure-treated lumber as well as composite decking
• Trex-approved fastener - confirmed compatible and approved by Trex for use with Trex composite decking, giving installers confidence in meeting manufacturer requirements
• T20 6-lobe drive with included driver bit - the matching drive system reduces cam-out and strip-out during installation, and the included bit means you can get to work right away
• Brown 01 color-matched head - blends with popular composite decking colors from leading manufacturers for a more concealed, finished appearance
• Curved-collated format - compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system or attachment, dramatically speeding up production on large 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, eliminating the need to mix and match different fasteners for different board brands and saving time on material selection and purchasing
• A finish worth showing off - the combination of the cap head, inverted upper threads, and Brown 01 color-matched paint delivers consistently flush, clean-looking results that enhance the overall appearance of the finished deck rather than detracting from it
• Built for high-volume installation efficiency - the curved-collated design pairs directly with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system, letting installers drive screws quickly and ergonomically without bending down to manually position each fastener
• Corrosion resistance you can count on long-term - the Quik Guard coating meets the equivalent of hot-dip galvanization (ASTM A153, Class D) in some exposures, protecting the fastener in pressure-treated lumber environments and helping the deck maintain its structural integrity over time

Frequently Asked Questions

What type of decking is the Deck-Drive DCU Composite Screw designed for?

The Deck-Drive DCU Composite Screw is engineered for use with composite or PVC decking. It is the go-to screw for all composite decking applications, eliminating the need to mix and match screws to the decking they are suited for. It is also an approved fastener by Trex for use with Trex composite decking.

What corrosion resistance does the Quik Guard coating provide?

The Quik Guard coating provides a level of corrosion resistance that is equivalent to hot-dip galvanization (ASTM A153, Class D) in some exposures, making it suitable for use in pressure-treated lumber as well as composite decking installations.

What tool is required to install the DCU234SBR01 collated screws?

These curved-collated screws install with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system or attachment. A T20 6-lobe driver bit is included with the package (replacement bit model BITTX20-PL-RC3).

How does the cap head design benefit the finished appearance of a composite deck?

The cap head prevents mushrooming and material from rising up above the deck surface, resulting in a smoother, clean-looking installation. Additionally, the Brown 01 color-matching painted head blends with popular decking manufacturers to provide a more concealed finish.
