Simpson #8 x 1 3/4 White 01 Composite Fascia Screws in Type 316 Stainless Steel are purpose-built for securing PVC trim and composite fascia boards, with approval specifically for the attachment of Trex Fascia Boards. The low-profile pancake head and deep T-20 6-lobe recess work together to deliver a clean, flush finish on exterior fascia installations, while Type 316 stainless steel construction provides severe-level corrosion resistance suited for demanding outdoor environments. A Type-17 point and coarse threads ensure fast, reliable engagement in composite and PVC fascia materials.

Key Features

• Approved for Trex Fascia Board attachment - gives you manufacturer-backed confidence when installing composite fascia, eliminating guesswork on fastener compatibility.
• Deep T-20 6-lobe recess - reduces cam-outs during driving so you get a cleaner installation with less tool slippage and surface damage (compatible bit part number: BIT20T-2-RC3, included).
• Type-17 point - pierces composite and PVC fascia materials quickly for fast starts and fewer pre-drilling steps.
• Low-profile pancake head - sits flush and resists pullover, leaving a neat, unobtrusive surface appearance on finished fascia work.
• Type 316 stainless steel - delivers severe-level corrosion resistance, making these screws dependable in coastal, high-moisture, and other harsh exterior conditions.
• White 01 head color - blends with light-colored fascia boards for a finished look that minimizes visible fastener contrast.

Why This Product

• Trex-approved for composite fascia - these screws carry specific approval for Trex Fascia Board attachment, so contractors and DIYers working with Trex products have a vetted fastener solution that meets manufacturer requirements.
• Severe-level corrosion protection built in - Type 316 stainless steel goes beyond standard exterior-grade fasteners, making these screws a strong choice for coastal builds, pool surrounds, and other environments where moisture and salt exposure accelerate corrosion.
• Engineered to reduce installation headaches - the combination of a Type-17 point for fast starts and a deep 6-lobe recess for reduced cam-outs means fewer stripped heads and cleaner results, especially when working overhead or at awkward angles on fascia runs.
• Color-matched for a professional finish - the White 01 pancake head keeps fasteners visually discreet on light composite and PVC fascia boards, reducing the need for touch-up work after installation.
