Simpson #7 x 2-1/2 in. Collated Trim-Head Screw, Type 305 Stainless Steel, Brown 05 (1,000-Qty) brings together the speed of collated fastening and the refined appearance of a low-profile trim head, making it a reliable choice for wood-to-wood deck board installation, dock and boardwalk construction, and other residential, commercial, and industrial decking projects. Engineered as part of the Simpson Quik Drive system, these screws are designed for problem-free performance when used with a compatible Quik Drive auto-feed attachment, delivering consistent results across high-volume fastening applications.

Key Features

• Trim-style head - sits low and discreet on the decking surface, producing a clean, finished appearance that keeps fasteners from drawing attention on the completed deck
• Type 305 stainless steel construction - provides high-level corrosion resistance, making these screws well suited for marine environments, boardwalks, and other high-exposure outdoor applications where long-term durability is essential
• Brown 05 color finish - blends with most major PVC and composite decking manufacturers' products, so fastener heads disappear into the deck surface rather than standing out
• Curved collation strips - hold screws up and away from the work surface, making moving and positioning the Quik Drive tool easier during installation and reducing fatigue on the job
• #2 square drive - delivers positive bit engagement that reduces cam-out and keeps the installation process smooth and efficient
• Sharp point with box threads - the sharp point starts the screw cleanly without pre-drilling, while box threads provide strong, secure holding power in wood substrates
• Driver bit included in every box - gets you started immediately without a separate trip for accessories; replacement bit model BIT2S is available when needed
• Specifically designed for Simpson Quik Drive system compatibility - ensures optimized, problem-free performance with the Quik Drive PRO250G2 auto-feed screw driving system or compatible attachment

Why This Product

• Aesthetics and corrosion resistance in one fastener - the Brown 05 trim head blends into composite and PVC decking surfaces while Type 305 stainless steel handles the demanding conditions of coastal, marine, and high-exposure environments without sacrificing appearance
• Built for high-speed collated installation - the curved collation design and sharp point work together with the Quik Drive auto-feed system to streamline deck board fastening, reducing installation time on large residential and commercial projects
• Practical value from the first screw to the last - a driver bit is included in each box, and the pointed collation strips simplify loading, so setup stays quick and workflow is rarely interrupted across a full 1,000-count installation
• Extensively tested for target application performance - Simpson designs and tests these collated trim-head screws specifically for decking, dock, and boardwalk applications, giving contractors and builders confidence in consistent, reliable results across every fastening point

Frequently Asked Questions

What tool is required to install the Simpson DTH212S305BR05 collated trim-head screws?

These screws are specifically designed to install with the Simpson Strong-Tie Quik Drive PRO250G2 auto-feed screw driving system or a compatible Quik Drive attachment. The curved collation design ensures problem-free system performance with this tool.

Why are these screws recommended for marine and high-exposure environments?

The DTH212S305BR05 screws are manufactured from Type 305 stainless steel, which provides high-level corrosion resistance. This makes them well suited for PVC or composite deck installations in marine or other high-exposure outdoor environments where standard steel fasteners may corrode prematurely.

How does the trim-head design benefit the finished appearance of a deck?

The trim-style head sits low and is less noticeable on the decking surface, delivering a clean, finished look compared to traditional larger-head screws. The Brown 05 color is also matched to blend with most major PVC and composite decking manufacturers, making the fasteners virtually disappear into the deck surface.

What drive type and replacement bit are compatible with these screws?

The DTH212S305BR05 uses a #2 square drive. Each box includes one driver bit. If a replacement bit is needed, the compatible model is the BIT2S.
