Product Description
The Simpson #7 x 2-1/4 in. Black Trim-Head Screw is purpose-built for fastening PVC and composite deck boards in marine, coastal, and high-exposure environments where corrosion resistance and a clean surface appearance both matter. Constructed from Type 316 stainless steel, these trim-head fasteners are engineered to hold up where standard screws fail, while the painted black head blends discreetly into the decking surface rather than drawing the eye. Each 70-piece pack includes a T15 driver bit so installation is ready to go from the start.
Key Features
- Trim-style head design - sits low and unobtrusive on the decking surface, delivering a cleaner, more finished appearance on wood, composite, and PVC deck boards
- Type 316 stainless steel construction - provides maximum corrosion protection in marine, seaside, and high-moisture environments where lesser fasteners degrade quickly
- Painted black finish - matched to blend with most major PVC and composite decking manufacturers, keeping the deck surface looking intentional and uniform
- T15 6-lobe drive - helps prevent driver-bit cam-out during installation, resulting in easier, more consistent driving and extended bit life
- Type-17 point - designed for fast, clean starts that reduce material tear-out and speed up the fastening process
- Coarse threads on approximately 2/3 of the shank - draw the deck board tightly down to the framing for a secure, rattle-free connection
- Includes one T15 driver bit - replacement bit model BIT15T-2-R2 is available separately, so you are never left searching for the right tool on the job
- Predrilling recommended near board ends - a simple precaution that prevents splitting and protects the integrity of your decking material
Why This Product
- Built for harsh environments - Type 316 stainless steel is the preferred material for marine and coastal fastening applications, offering a level of corrosion resistance that carbon steel and lower-grade stainless simply cannot match in salt-laden or high-moisture conditions.
- Appearance matters as much as performance - the combination of a slim trim-style head and a color-matched black finish means fasteners stay in the background, letting the decking itself take center stage on docks, boardwalks, and residential or commercial deck projects.
- Engineered to reduce installer frustration - the 6-lobe T15 drive and Type-17 point work together to minimize cam-out and improve bite on entry, cutting down on stripped screws and wasted time whether you are a professional contractor or a first-time deck builder.
- Versatile across decking applications - suitable for wood decking, select composite decking materials, docks, and boardwalks, making this a single fastener solution that covers a range of outdoor structural and finish-decking projects.

Frequently Asked Questions
- What type of decking material are these screws compatible with?
- These trim-head screws are designed to fasten wood decking and some composite decking materials. They are particularly well-suited for PVC and composite deck boards in marine or high-exposure environments where superior corrosion resistance is required.
- Why is Type 316 stainless steel important for decking applications?
- Type 316 stainless steel provides maximum corrosion protection, making these screws especially appropriate for marine, seaside, and high-exposure environments. Standard fasteners can degrade quickly in these conditions, while Type 316 stainless steel is engineered to withstand prolonged exposure to moisture and salt-laden air.
- What drive bit is required, and is one included?
- These screws use a T-15 6-lobe drive, which helps prevent driver-bit cam-out for easier driving and longer bit life. Each 70-piece pack includes one T15 driver bit. If you need a replacement bit, the compatible model is BIT15T-2-R2.
- Should I predrill before installing these screws near board ends?
- Yes, predrilling is recommended near board ends to prevent splitting. The Type-17 point is designed for fast starts, and the coarse threads on approximately 2/3 of the shank draw decking material tightly to the framing, but predrilling near edges helps ensure a clean, split-free installation.
