Simpson Trim-Head Decking Screws are collated, sharp-point fasteners manufactured from Type 305 stainless steel for high-level corrosion resistance in marine and high-exposure environments where PVC or composite decks are installed. Designed with a low-profile trim-style head for a clean, finished appearance on deck surfaces, these #7 x 2 in. screws feature curved collation and a #2 square drive for fast, consistent installation with the Simpson Strong-Tie Quik Drive PRO250G2 auto-feed screw driving system or compatible attachment - making them a reliable choice for docks, boardwalks, and coastal decking projects.

Key Features

• Trim-style head - sits low and inconspicuous on the decking surface, delivering a polished, professional finish that lets the deck material take center stage
• Type 305 stainless steel construction - provides high-level corrosion resistance to stand up to moisture, salt air, and the demanding conditions of marine and waterfront installations
• Curved collation - compatible with auto-feed screw driving systems, enabling rapid, consistent fastener placement across large deck and boardwalk surfaces
• #2 square drive - reduces cam-out during driving for a more secure bit engagement and cleaner installation, especially at high volumes
• Sharp point - penetrates PVC and composite decking materials without pre-drilling, saving time on the job
• Box threads - designed to pull fasteners snug into decking boards for a tight, secure hold
• Driver bit included - gets you started immediately out of the box, with replacement bit model BIT2S available separately when needed

Why This Product

• Built for harsh environments - Type 305 stainless steel provides the corrosion resistance required for docks, boardwalks, and coastal decking where standard fasteners would quickly degrade from moisture and salt exposure
• Designed for high-speed, high-volume installation - curved collation pairs directly with the Simpson Strong-Tie Quik Drive PRO250G2 system, dramatically reducing installation time on large composite and PVC decking projects
• Finish-quality results without extra steps - the trim-style head leaves a minimal footprint on the deck surface, eliminating the need for plugs or covers and giving the finished deck a cleaner, more refined appearance
• A complete, job-ready package - each box includes 2,000 collated screws and a driver bit, so crews can move from delivery to installation without hunting for additional accessories
