Simpson #7 x 2-1/4" Trim-Head Decking Screw in Tan 04 with T15 6-Lobe Drive and Type 316 Stainless Steel is engineered for fastening PVC and composite decking in demanding outdoor and marine environments where corrosion resistance is non-negotiable. Featuring a low-profile trim head and a painted Tan 04 finish matched to blend with popular composite decking surfaces, these coarse-thread screws deliver a clean, nearly invisible fastening result that holds decking material tightly to framing. Type 316 stainless steel construction makes them well-suited for seaside installations, high-moisture zones, and any application where long-term durability against salt air and harsh weather is required.

Key Features

• Type 316 Stainless Steel material - provides superior corrosion resistance in marine, coastal, and high-exposure outdoor environments where standard fasteners would fail prematurely
• Trim Head design with 0.230" head diameter - sits flush and low-profile on the decking surface, reducing visibility and creating a cleaner finished appearance on PVC and composite decks
• Tan 04 painted head color - blends with most major PVC and composite decking manufacturers' board colors, helping fasteners disappear into the deck surface for a polished look
• T15 6-Lobe drive system - resists cam-out during driving, resulting in easier installation, reduced installer fatigue, and longer bit life compared to traditional drive types
• Type-17 cutting point - bites into material quickly for fast starts, reducing the effort needed to begin driving and minimizing the risk of the screw wandering on the surface
• Coarse threads - draw decking boards and other materials tightly down against the framing for a secure, gap-free connection that resists movement and squeaking over time
• #7 screw size at 2-1/4" length - sized appropriately for fastening composite and PVC decking boards to standard framing members with reliable holding power

Why This Product

• Built for marine and coastal deck projects - Type 316 stainless steel is the material of choice for seaside and high-exposure installations where salt air, moisture, and chemicals accelerate corrosion in lesser fasteners, making these screws a reliable long-term solution
• Designed to disappear into the deck surface - the combination of a trim-style low-profile head and a Tan 04 color-matched painted finish means fasteners blend with the decking rather than standing out, delivering a professional-grade aesthetic result
• Engineered for tool-friendly installation - the 6-lobe T15 drive prevents bit cam-out and the Type-17 point speeds up starts, so installers work faster with less driver bit replacement on large deck projects
• Versatile fit for the composite decking market - available in 13 colors to match most major PVC and composite decking manufacturers, making it straightforward to select the right color for virtually any decking brand or color palette

Frequently Asked Questions

What type of decking is this screw designed for?

These trim-head screws are specifically designed for use with PVC and composite decking installations. The Tan 04 painted head is color-matched to blend with most major PVC and composite decking manufacturers' products, and the Type 316 stainless steel construction makes them suitable for both standard outdoor and high-exposure coastal environments.

Why choose Type 316 stainless steel over other finishes for decking screws?

Type 316 stainless steel offers superior corrosion resistance compared to standard stainless or coated fasteners, particularly in marine environments, seaside applications, and areas with high moisture or chemical exposure. It is the recommended choice when the deck will face salt air, standing water, or other harsh conditions that could degrade lesser materials over time.

Do I need to predrill holes before driving these screws?

Predrilling is recommended near board ends to help prevent splitting of the decking material. The Type-17 cutting point is designed for fast starts in field applications, but taking the extra step near edges and ends helps protect the integrity of the boards during installation.

What driver bit is needed to install these screws?

These screws use a T15 6-Lobe drive, which requires a compatible T15 6-lobe (Torx-style) driver bit. The 6-lobe design is specifically chosen to reduce cam-out during driving, helping extend bit life and making the installation process faster and more controlled compared to Phillips or square drive alternatives.
