Simpson #8 x 1 3/4 Tan Composite Fascia Screws in Type 316 Stainless Steel are specialty fasteners engineered for the secure attachment of composite and PVC fascia boards, including Trex Fascia Boards. Every design detail - from the low-profile pancake head to the Type-17 self-starting tip - works together to deliver a clean, durable fascia installation that resists pullover, warping, buckling, and oil-canning. Type 316 stainless steel construction provides severe-level corrosion resistance, making these screws a dependable choice for outdoor fascia applications exposed to moisture and harsh weather conditions. Each pack includes a matching T-20 6-lobe driver bit so you have what you need to get started right away.

Key Features

• Approved for attachment of Trex Fascia Boards - gives you manufacturer-backed confidence that these screws are the right fastener for one of the most widely used composite fascia systems.
• Deep T-20 6-lobe recess - reduces cam-outs during driving, so you spend less time correcting slips and more time completing a professional-looking installation.
• Type-17 point - enables fast, clean starts without pre-drilling, speeding up the installation process and reducing the risk of material damage.
• Low-profile pancake head (0.400 in. diameter) - sits flush against the fascia surface to resist pullover and help prevent warping, buckling, and oil-canning in the finished board.
• Type 316 stainless steel material and finish - delivers severe-level corrosion resistance, keeping fasteners structurally sound in demanding outdoor environments where moisture and weather exposure are constant.
• Tan head color - blends with natural wood-tone composite fascia boards for a finished appearance that minimizes visible fastener contrast.
• Includes matching T-20 6-lobe driver bit - the correct bit is supplied with the screws, ensuring proper seating and reducing the chance of cam-out right out of the box.

Why This Product

• Purpose-built for composite and PVC fascia installation - unlike general-purpose screws, these fasteners are specifically designed to secure fascia material while accommodating the natural expansion and contraction of composite boards, helping prevent common issues like buckling and oil-canning.
• Trex-approved for reliable compatibility - the T08175FS75TN carries explicit approval for Trex Fascia Board attachment, removing guesswork when specifying fasteners for one of the most popular composite fascia products on the market.
• Severe-level corrosion resistance from Type 316 stainless steel - for fascia installations in coastal, humid, or otherwise demanding outdoor settings, Type 316 material provides a meaningful step up in protection compared to standard stainless options.
• Everything needed to drive the screws is included - the pack comes with the matching T-20 6-lobe driver bit, so installers are not left sourcing additional tooling before the job can begin.

Frequently Asked Questions

What makes these screws suitable for composite fascia board installations?

These fascia screws are specially designed to secure fascia material firmly in place while allowing boards to expand and contract due to environmental conditions. The low-profile pancake head resists pullover, and the Type-17 tip enables fast starts, together preventing head pullover, broken screws, warping, buckling, and oil-canning during installation.

What level of corrosion resistance do these screws provide?

These screws are manufactured from Type 316 stainless steel, which provides severe-level corrosion resistance, making them well-suited for demanding outdoor environments such as fascia board installations exposed to moisture and weather.

Are these screws approved for use with Trex Fascia Boards?

Yes. The Simpson T08175FS75TN fascia screw is specifically approved for the attachment of Trex Fascia Boards.

Do I need any additional tools or bits to install these screws?
