Simpson #8 x 1 3/4 Red Composite Fascia Screws in Type 316 Stainless Steel are engineered specifically for securing composite and PVC fascia boards with a clean, lasting result. The low-profile pancake head, Type-17 tip, and deep T-20 6-lobe recess work together to make installation faster and more precise, while Type 316 stainless steel construction delivers severe-level corrosion resistance suited for demanding outdoor and coastal environments. With approval for attachment of Trex fascia boards and a red head color that blends discreetly into finished fascia, these screws are a purpose-built solution for professional composite and PVC trim installations.

Key Features

• Approved for attachment of Trex Fascia Boards - gives installers confidence that the fastener meets manufacturer requirements for a compliant, warranted installation.
• Deep T-20 6-lobe recess - reduces cam-outs during driving, protecting both the screw head and the fascia board surface for a cleaner finish (compatible bit part number: BIT20T-2-RC3).
• Type-17 point - enables fast, self-starting penetration without pre-drilling, saving time on every board.
• Low-profile pancake head - resists pullover by distributing load across a wider bearing surface, keeping the fascia board held securely without breaking through the material.
• Type 316 stainless steel construction - provides severe-level corrosion resistance, making these screws well-suited for high-moisture, saltwater, and other corrosive outdoor environments.
• Red head color - designed to blend with fascia board finishes, minimizing the visual impact of fastener heads on the completed installation.
• Coarse threads - provide strong holding power in composite and PVC fascia materials, reducing the risk of fastener back-out over time.

Why This Product

• Purpose-built for composite and PVC fascia - unlike general-purpose screws, every design element here - from the pancake head geometry to the Type-17 tip - is tailored to the specific demands of fascia board attachment, reducing installation problems and improving the finished appearance.
• Trex approval backs up the performance claim - these screws carry explicit approval for attachment of Trex fascia boards, making them a straightforward, specification-compliant choice for installers working with that product line.
• Severe-level corrosion resistance for long-term durability - Type 316 stainless steel goes beyond standard corrosion protection, making these fasteners a sound investment for exterior applications where moisture, salt air, or chemical exposure would degrade lesser materials over time.
• Includes the driver bit needed for the job - the T-20 6-lobe driver bit is included with each pack, so installers have the correct tooling on hand from the start and can avoid cam-outs that can mar a fascia board surface.
