The Simpson Deck-Drive DCSD Composite-to-Steel Collated Screw, #10 x 2-3/8 in., Quik Guard Gray 01 is engineered by Simpson for one specific job: fastening composite decking boards directly to steel deck framing quickly, cleanly, and without the extra step of predrilling. With a pilot point tip, variable thread design, and cap head profile, this collated fastener is built to deliver a professional finish on composite deck installations while keeping job-site workflow moving at full speed.

Key Features

• Drives through double 14 ga. steel box beam without predrilling - saves time on every board by eliminating a separate drilling step, letting crews fasten composite decking directly to steel framing in one pass.
• Cap head with no mushrooming - the low-profile cap head sits flush and clean at the deck surface, so the finished result looks polished without requiring touch-up or grinding.
• Plastic strip collation for use with the Quik Drive PRO300SG2 decking system - the Quik Drive tool holds each screw securely as it drills through the metal joist, producing a more consistent depth and angle across every fastener for a uniform deck surface.
• Pilot point tip and variable thread design - the pilot point self-starts in composite material and steel without wandering, while the variable thread pulls the decking board tight to the framing for a secure, rattle-free connection.
• #2 undersized square drive with included driver bit - the undersized drive geometry grips the bit more securely, reducing cam-out during installation, especially important when driving fasteners with protective coatings; a compatible bit is included so the tool is ready to run immediately.
• Quik Guard coating for medium-level corrosion resistance - provides lasting protection in typical outdoor decking environments; note that this coating is not recommended for marine environments where salt exposure is a factor.
• Gray 01 color matched for composite decking - the screw head blends with gray-toned composite boards so fasteners recede visually into the deck surface rather than standing out.
• 1,000 screws per package - the high-count collated package keeps the auto-feed tool loaded longer, reducing downtime for reloading on larger decking projects.

Why This Product

• No predrilling required through steel framing - the pilot point and variable thread design allow this screw to penetrate double 14 ga. steel box beams in a single step, cutting labor time significantly on composite-to-steel deck builds compared to a traditional drill-then-fasten workflow.
• Purpose-built for composite decking on steel structure - unlike general-purpose deck screws, the DCSD is specifically engineered for the composite-to-steel application, matching head geometry, thread pitch, and coating to the demands of that material combination.
• System-matched collation for consistent, repeatable results - designed to work with the Simpson Quik Drive PRO300SG2, the plastic strip collation and undersized square drive work together as a complete system, reducing installer fatigue and delivering uniform fastener depth across an entire deck surface.
• Color-coordinated finish that preserves deck aesthetics - the Gray 01 Quik Guard-coated cap head is sized and colored to sit flush and blend with gray composite boards, keeping the focus on the deck surface rather than the hardware.

Frequently Asked Questions

Do these screws require predrilling through steel framing?

No. The Deck-Drive DCSD screw drives easily through double 14-gauge steel box beams without predrilling, saving time and streamlining the installation process.

What Quik Drive tool is compatible with these collated screws?

These screws are compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 decking system, which holds the screw securely as it drills through the metal joist for a more consistent installation.

What level of corrosion resistance does the Quik Guard coating provide?

The Quik Guard coating provides medium-level corrosion resistance. These screws are not recommended for use in marine environments.

How do I match the Gray 01 color to my composite decking material?

Simpson Strong-Tie provides a Composite-Decking Color Cross-Reference guide to help match screw colors to your decking material. See the Downloads and Resources section below for the color guide PDF.
