The Simpson Trim-Head Screw #7 x 1-5/8 in. 6-Lobe Drive Type 316 Stainless Tan is a purpose-built decking fastener designed for marine, seaside, and high-exposure environments where PVC or composite deck installations demand maximum corrosion protection. Constructed from Type 316 stainless steel, this screw delivers a clean, low-profile finish on the deck surface thanks to its trim-style head, which is available in a tan color matched to blend with most major PVC and composite decking manufacturers. The T-15 6-lobe drive, Type-17 point, and coarse-thread shank work together to make installation fast, secure, and cam-out-free - whether you are fastening composite deck boards or wood decking to framing on a dock, boardwalk, or residential deck.

Key Features

• Trim-Style Head Design - The low-profile head sits discreetly on the decking surface, giving finished composite and PVC deck installations a clean, polished look with minimal visual distraction.
• Type 316 Stainless Steel Construction - Provides maximum corrosion protection in marine, salt-air, and high-moisture environments where standard stainless grades fall short, keeping fasteners secure and rust-free over the long term.
• Tan Color-Matched Finish - Painted head blends with most major PVC and composite decking manufacturers in tan tones, reducing the appearance of fasteners across the full deck surface.
• T-15 6-Lobe Drive - Helps prevent driver-bit cam-out during installation, resulting in easier, more controlled driving and longer driver-bit life on the job.
• Type-17 Point - Self-starting tip allows fast engagement with decking material without pre-drilling in field areas, reducing installation time and effort.
• Coarse Threads on Approximately 2/3 of the Shank - Draws the decking material tightly and securely against the framing for a firm, gap-free connection with each fastener.
• T-15 Driver Bit Included - A matching T-15 driver bit comes in the package, so installers can get started right away without sourcing a separate bit (replacement bit model BIT15T-2-R2).

Why This Product

• Built for Harsh, High-Exposure Environments - Type 316 stainless steel is the material of choice for marine and coastal deck installations, offering a level of corrosion resistance that protects both the fastener and the surrounding decking in conditions where salt air and moisture are constant concerns.
• A Cleaner Finished Deck Surface - The trim-style head profile and color-matched tan finish work together to make fasteners far less noticeable once installed, a meaningful advantage on high-visibility PVC or composite deck projects where appearance matters as much as performance.
• Engineered to Speed Up Installation - The combination of a Type-17 self-starting point and a 6-lobe drive that resists cam-out means fewer interruptions, less wasted effort, and a smoother workflow across composite, PVC, and wood decking applications including docks and boardwalks.
• Versatile Across Common Decking Applications - Suitable for wood decking, composite deck boards, PVC deck installations, and dock or boardwalk construction, making this a practical fastener choice for contractors and builders working across multiple project types.

Frequently Asked Questions

Why is Type 316 stainless steel recommended for this application?

Type 316 stainless steel provides maximum corrosion protection, making these screws ideal for marine, seaside, and other high-exposure environments where PVC or composite decks are installed. It offers superior resistance compared to standard stainless grades, which is especially important in environments with salt air or moisture exposure.

Do I need to pre-drill before installing these screws?

Pre-drilling is not required in the field area, as the Type-17 point is designed for fast, self-starting installation. However, pre-drilling is recommended near board ends to prevent splitting the decking material.

What driver bit is needed, and is one included?

These screws use a T-15 6-lobe drive. One T-15 driver bit is included with the 70-piece pack. If you need a replacement bit, the compatible model is BIT15T-2-R2.

How does the Tan color match up with PVC and composite decking brands?

The Tan painted head is designed to blend with most major PVC and composite decking manufacturers. Simpson offers Trim-Head screws in 13 colors, allowing you to select the closest match to your specific decking product for a clean, low-profile appearance on the finished deck surface.
