Simpson #7 x 2-1/4" Trim-Head Decking Screw in Brown 05 with T15 6-Lobe Drive and Type 305 Stainless Steel finish is engineered for PVC and composite deck installations where a clean, low-profile fastening solution is required. The painted Brown 05 head blends seamlessly with popular decking surfaces, while the Type 305 Stainless Steel construction delivers superior corrosion resistance in marine and high-exposure outdoor environments. Whether you're building a coastal deck, replacing weathered fasteners, or working with premium composite boards, this trim-head screw combines professional aesthetics with long-lasting durability.

Key Features

• Trim Head design with 0.230" head diameter - sits low and discreet on the decking surface, producing a clean, finished look that complements premium PVC and composite boards
• Type 305 Stainless Steel material and finish - provides superior corrosion resistance in marine, coastal, and high-exposure outdoor environments where standard steel fasteners would rust or stain
• Brown 05 painted head color - matched to blend with most major PVC and composite decking manufacturers, reducing the visual impact of fasteners on the finished deck surface
• T15 6-Lobe drive - reduces driver-bit cam-out during installation, resulting in easier, faster driving and extended bit life on the job
• Type-17 point - aggressive point design allows fast, self-starting penetration into decking material without pre-drilling in most field conditions
• Coarse threads - draw decking boards and composite material tightly down to the framing for a firm, secure hold and a flush surface finish
• #7 screw size at 2-1/4" length - sized appropriately for standard PVC and composite deck board thickness over dimensional lumber framing
• Approximately 138 screws per pound - makes it easy to estimate quantities needed based on your project scope and purchase accordingly

Why This Product

• Built for marine and high-exposure environments - Type 305 Stainless Steel construction resists the accelerated corrosion that coastal humidity, salt air, and moisture-rich conditions cause in ordinary fasteners, protecting the structural integrity of your deck over time.
• A color-matched finish that disappears into the deck - the Brown 05 painted head is designed to blend with most major composite and PVC decking brands, so fasteners don't distract from the look of your finished surface.
• Less cam-out means a faster, cleaner install - the T15 6-Lobe drive keeps the bit engaged throughout the drive cycle, reducing stripped heads and driver slippage that slow down installation and damage material.
• The right screw for composite and PVC deck applications - the combination of trim head profile, Type-17 self-starting point, and coarse threads is specifically suited to the characteristics of composite and PVC deck boards, making this a purpose-built fastener rather than a general-use screw.

Frequently Asked Questions

What decking materials are these trim-head screws designed to work with?

These screws are designed for use with PVC and composite deck boards. The trim head profile, coarse threads, and Type-17 point are specifically suited to the material properties of composite and PVC decking installed over standard framing lumber.

Why choose Type 305 Stainless Steel for deck fasteners?

Type 305 Stainless Steel provides superior corrosion resistance compared to standard coated or zinc-plated fasteners, making it appropriate for marine environments, coastal installations, and other high-exposure outdoor applications where moisture and salt air would cause ordinary screws to rust or stain the decking surface.

Is pre-drilling required when installing these screws?

The Type-17 point is designed for fast starts and self-starting penetration into decking material. However, pre-drilling is recommended near board ends to prevent splitting of the deck boards.

What does the Brown 05 color designation mean?

Brown 05 refers to the specific painted color applied to the screw head. These painted heads are available in 13 colors matched to blend with most major PVC and composite decking manufacturers, so the fastener blends into the deck surface for a cleaner finished appearance.
