Simpson #8 x 1 3/4 Red 01 Composite Fascia Screws in Type 316 Stainless Steel are purpose-built fasteners engineered for the secure attachment of Trex fascia boards and PVC trim, delivering a clean, professional finish in exterior applications where long-term durability and corrosion resistance are non-negotiable. The low-profile pancake head and Type-17 point work together to make installation fast and reliable, while the deep T-20 6-lobe recess virtually eliminates cam-outs for a consistent, damage-free drive every time.

Key Features

• Approved for Trex Fascia Board attachment - gives you confidence that these screws meet the requirements for one of the most widely used composite fascia systems, removing guesswork from the jobsite.
• Deep T-20 6-lobe recess (compatible bit: BIT20T-2-RC3) - reduces cam-outs during driving, protecting both the screw head and the fascia board surface for a cleaner finished result.
• Type-17 point - bites into material quickly for fast, accurate starts without pre-drilling, saving time on repetitive fascia runs.
• Low-profile pancake head - resists pullover and sits flush against the fascia surface, creating a neat appearance without raised edges that could snag or lift the board.
• Type 316 stainless steel construction - provides severe-level corrosion resistance, keeping fasteners structurally sound through prolonged exposure to moisture, salt air, and harsh exterior conditions.
• Coarse thread pattern - bites firmly into PVC trim and composite fascia materials, holding boards securely in place and reducing the risk of loosening over time.
• Red 01 head color - coordinates with compatible fascia board finishes so fastener heads blend into the installation rather than standing out as an eyesore.

Why This Product

• Built specifically for composite fascia work - unlike general-purpose screws, these fasteners carry explicit approval for Trex fascia board attachment and are suited for PVC trim applications, meaning they are matched to the demands of the job rather than adapted from an unrelated use case.
• Severe-level corrosion resistance where it counts most - Type 316 stainless steel is the material of choice for exterior fasteners exposed to moisture and environmental stress, making these screws a sound long-term investment for any outdoor fascia project.
• A drive system designed to protect your work - the deep T-20 6-lobe recess pairs with the included driver bit to reduce cam-outs, keeping tool energy focused on the screw and off the surrounding fascia surface during installation.
• Complete, ready-to-use package - each pack includes the matched T-20 6-lobe driver bit so you have the right tool on hand from the start, reducing trips back to the supply house mid-project.
