Simpson Deck-Drive DCSD Composite-to-Steel Screw, #10 x 2-3/8 in., Quik Guard Brown 01, Collated, 1,000-Qty is purpose-built by Simpson for fastening composite decking directly to steel deck framing. Collated on plastic strip for seamless use with an auto-feed Quik Drive system, these #10 screws cut through double 14-gauge steel box beams without predrilling and leave a clean, flush deck surface with no mushrooming - making them a reliable choice for professional deck builders working with composite boards over metal substructures.

Key Features

• Drives through double 14 ga. steel box beam without predrilling - saves time on every fastening point and eliminates a separate drilling step across the entire deck surface.
• Pilot point tip with variable thread design - starts cleanly and pulls the composite board tight to the steel framing for a secure, gap-free connection.
• Cap head design with no mushrooming - leaves a neat, finished appearance at each fastener location so the deck surface looks professional without post-installation cleanup.
• Quik Drive system compatibility holds the screw securely during driving - reduces wobble and misalignment through the metal joist for a more consistent installation from start to finish.
• #2 undersized square drive with included driver bit - delivers secure bit engagement and reduces cam-out, especially valuable when driving fasteners with protective coatings at high speed.
• Quik Guard coating provides medium-level corrosion resistance - suited for typical exterior deck environments, though not intended for marine or coastal applications where higher corrosion exposure is present.
• Brown 01 color - blends with composite decking boards in matching tones; a Simpson Composite-Decking Color Cross-Reference guide is available to help match screw color to specific decking products.

Why This Product

• Eliminates predrilling into steel framing - the pilot point and variable thread design allow these screws to self-start through double 14-gauge steel box beams, cutting labor time and keeping crews moving on large decking projects.
• Engineered specifically for composite-to-steel applications - unlike general-purpose deck screws, the Deck-Drive DCSD is designed for the precise pairing of composite board material and steel substructure, reducing the guesswork of fastener selection.
• Auto-feed collation for faster, more consistent installation - plastic strip collation works with the Quik Drive PRO300SG2 decking system to hold each screw on axis during driving, improving placement accuracy and reducing fatigue over a full day of decking work.
• Complete fastening solution out of the box - a driver bit is included with every package, so work can begin immediately without sourcing a separate bit, and replacement bits (model BIT2SU) are available when needed.
