Simpson #7 x 1-5/8" Trim-Head Decking Screw in White 01 with T15 6-Lobe Drive and Type 316 Stainless Steel is engineered for installers who demand a clean, low-profile finish on PVC and composite deck surfaces in demanding outdoor and coastal environments. The Type 316 stainless steel construction delivers superior corrosion resistance against saltwater, moisture, and harsh chemical exposure, making these screws a dependable choice for seaside and high-exposure deck installations. The White 01 painted head is color-matched to blend seamlessly with most major composite and PVC decking brands, keeping the finished deck surface looking polished and professional.

Key Features

• Trim-head design with 0.230" head diameter - sits flush and inconspicuously on the decking surface, delivering a clean, finished appearance that minimizes visible hardware on composite and PVC boards
• Type 316 stainless steel material and finish - provides superior corrosion resistance in marine, seaside, and high-humidity environments where standard stainless or coated screws may fail prematurely
• White 01 painted head - color-matched to blend with most major PVC and composite decking manufacturers across 13 available colors, so fasteners virtually disappear into the deck surface
• T15 6-lobe drive - resists driver-bit cam-out during installation, allowing faster, cleaner driving with less effort and extended bit life compared to traditional Phillips or square drives
• Type-17 point - enables fast, self-starting penetration into decking material without pre-drilling on most applications, saving installation time
• Coarse threads - draw decking boards and substrate tightly together for a secure, gap-free connection between the deck surface and framing
• 1-5/8" length, #7 screw size - sized appropriately for composite and PVC decking applications, providing solid fastening depth without over-penetrating thinner framing members
• Includes T15 driver bit (replacement model BIT15T-2-R2) - ready to drive right out of the package, reducing the need to source additional tooling before starting the job

Why This Product

• Purpose-built for coastal and marine deck applications - Type 316 stainless steel is the recommended material for seaside environments where saltwater spray and prolonged moisture exposure would degrade lower-grade fasteners, protecting both the fastener and the deck structure long-term
• Visually disappears into the deck surface - the combination of the trim-head profile and White 01 color-matched painted head means fasteners blend with the surrounding decking rather than standing out as eyesores, preserving the aesthetic of premium composite or PVC deck installations
• Designed to reduce cam-out and installer fatigue - the T15 6-lobe drive system grips the bit securely during driving, which translates to fewer stripped heads, less wasted material, and a faster, more consistent installation pace across large deck projects
• Compatible with most major composite and PVC deck brands - available in 13 head colors to match a wide range of decking product lines, making these screws a versatile fastening solution rather than a single-brand accessory

Frequently Asked Questions

What type of decking material are these trim-head screws designed for?

These screws are designed for use with PVC and composite decking. The trim-head profile and color-matched White 01 painted head are specifically intended to blend with most major PVC and composite decking manufacturers, providing a clean, low-profile appearance on the finished deck surface.

Why is Type 316 stainless steel recommended for deck fasteners in coastal or marine environments?

Type 316 stainless steel offers superior corrosion resistance compared to standard stainless grades, making it the appropriate choice for seaside and high-exposure outdoor applications where fasteners are subject to saltwater, moisture, and other corrosive conditions. This helps maintain structural integrity and appearance over the long term in demanding environments.

Is pre-drilling required when installing these screws?

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

What driver bit do these screws require, and is one included?

These screws use a T15 6-lobe drive. A T15 driver bit is included with the product. If a replacement bit is needed, the compatible replacement model is BIT15T-2-R2.
