The Simpson Deck-Drive DCU Composite Screw (#10 x 2-3/4 in., Tan 01, Collated, 1000-Pack) by Simpson is engineered specifically for composite and PVC decking installations, delivering clean, professional fastening results across all major composite decking brands without the need to mix and match fasteners. Featuring a color-matching Tan 01 painted cap head, collated curved strips for use with the Quik Drive auto-feed system, and Quik Guard coating for outstanding corrosion resistance, this screw is the one versatile solution built to handle every composite deck board application with precision and speed.

Key Features

• Tri-lobe thread design - minimizes stress and damage to composite board material during driving, preserving the integrity of the deck surface for a cleaner finished result
• Inverted upper threads - clear excess material as the screw seats, ensuring a consistent, flush installation every time and reducing the chance of surface imperfections
• Type-17 point - self-piercing tip penetrates composite decking quickly for faster starts and reduced driving effort, speeding up installation across large deck projects
• Cap head design - prevents mushrooming and material from rising above the deck surface, leaving a smooth, professional-looking finish without additional cleanup
• Tan 01 color-matching painted head - blends with popular composite decking surfaces for a more concealed, aesthetically refined appearance
• Quik Guard coating - provides corrosion resistance equivalent to hot-dip galvanization (ASTM A153, Class D) in some exposures, making it suitable for use alongside pressure-treated lumber
• Trex-approved fastener - meets Trex composite decking requirements, giving contractors and homeowners confidence in a verified, compatible choice for Trex installations
• T20 6-lobe drive with included driver bit - the torque-efficient drive system reduces cam-out and bit wear, with a compatible replacement bit (model BITTX20-PL-RC3) available for extended use
• Curved collation format - works directly with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system or attachment, enabling high-volume decking installations with less bending and fatigue

Why This Product

• One screw for all composite decking types - the Deck-Drive DCU eliminates the confusion and inefficiency of maintaining multiple fastener types on the job site, serving as a single go-to composite decking screw regardless of the brand of decking being installed
• Engineered for a clean, surface-level finish - the combination of the cap head, inverted upper threads, and tri-lobe design works together to prevent surface damage, material mushrooming, and inconsistent seating, resulting in a deck that looks polished and professional
• Built for high-volume, efficient installation - collated curved-strip format and compatibility with the Quik Drive auto-feed system allow crews to drive screws continuously without stopping to reload, cutting labor time on large composite deck builds
• Verified corrosion performance in demanding conditions - the Quik Guard coating delivers hot-dip galvanization-equivalent corrosion resistance (ASTM A153, Class D) in some exposures, making these screws a dependable choice even when fastening into pressure-treated substructure materials

Frequently Asked Questions

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

The Deck-Drive DCU Composite screw is engineered specifically for 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 applications.

What tool is required to install these 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 in the package, with the replacement bit model BITTX20-PL-RC3 available separately.

How does the cap head design benefit the finished deck appearance?

The cap head prevents mushrooming and material from rising up above the deck surface, resulting in a smoother, clean-looking installation. Additionally, the Tan 01 color-matching painted head is designed to blend with popular decking manufacturers, providing a more concealed and aesthetically consistent finish.
