The Simpson Deck-Drive DCU Composite Screw - #10 x 2-3/4 in., Type 316 Stainless Steel, Tan 01 (Collated) is engineered by Simpson to deliver clean, professional fastening results across all types of composite and PVC decking applications. With a precision tri-lobe thread design, a Type-17 point, and a color-matching Tan 01 cap head, this screw eliminates the need to mix and match fasteners for different decking materials - offering greater ease of installation, consistent seating, and severe-level corrosion resistance in one purpose-built solution. Curved collation makes it fully compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system, and a T20 6-lobe driver bit is included.

Key Features

• Tri-lobe thread design - reduces damage to the composite board while driving, protecting the integrity and appearance of the decking surface
• Inverted upper threads - clear excess material during installation so the screw seats properly and consistently every time, eliminating uneven or proud fasteners
• Type-17 point - penetrates composite decking with ease for faster starts, reducing installation time and driver bit wear
• Cap head design - prevents mushrooming and keeps material flush with the deck surface, delivering a smooth, clean-looking finish without raised edges
• Type 316 stainless steel construction - provides severe-level corrosion resistance for long-term performance in demanding outdoor environments exposed to moisture and the elements
• Tan 01 color-matching painted head - blends with popular composite decking for a more concealed, finished appearance that complements the deck's look
• Trex-approved fastener - meets Trex composite decking requirements, giving installers and homeowners confidence in code-compliant, manufacturer-sanctioned results
• Curved collation with T20 6-lobe drive - works directly with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system, speeding up large-scale deck installations; driver bit included

Why This Product

• One screw for all composite decking types - the Deck-Drive DCU is designed to work across composite and PVC decking applications without the need to mix and match fasteners, simplifying material planning and reducing jobsite confusion
• A finish that disappears into the deck - the Tan 01 painted cap head is specifically sized and color-matched to blend with popular composite decking manufacturers, so fasteners stay out of sight and the deck surface takes center stage
• Built for coastal and high-moisture environments - Type 316 stainless steel delivers severe-level corrosion resistance, making these screws a dependable long-term choice for decks near water, in humid climates, or in other corrosive outdoor settings
• Engineered for speed and collated convenience - curved collation and compatibility with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system mean faster drives, less fatigue, and more boards installed per hour compared to loading screws individually
