Simpson #8 x 1 3/4 Tan 03 Composite Fascia Screws, 316 Stainless Steel are purpose-engineered fasteners from Simpson designed for clean, durable attachment of PVC trim and composite fascia boards. Built from Type 316 stainless steel for severe-level corrosion resistance, these screws combine a low-profile pancake head with a deep T-20 6-lobe recess to deliver pullover-resistant, cam-out-reduced installations on exterior fascia applications - including specifically approved use with Trex Fascia Boards. The Tan 03 head color blends with the fascia surface for a finished, professional appearance.

Key Features

• Approved for attachment of Trex Fascia Boards - gives you confidence that this fastener meets manufacturer requirements for composite fascia installations, removing guesswork from the job.
• Type 316 stainless steel construction - provides severe-level corrosion resistance, making these screws a reliable long-term choice for exterior applications exposed to harsh environmental conditions.
• Low-profile pancake head resists pullover - keeps the fastener seated securely against the fascia surface without tearing through the material, preserving the integrity of the board.
• Deep T-20 6-lobe recess reduces cam-outs - the 6-lobe drive geometry maintains bit engagement under torque, helping you drive screws cleanly and consistently with less wasted effort or stripped heads.
• Type-17 point enables fast starts - the self-starting tip bites into material quickly, reducing the need to pre-drill and speeding up installation on fascia runs.
• Tan 03 head color - coordinates with the fascia surface to minimize the visual impact of each fastener, supporting a clean, finished exterior look.
• Includes T-20 6-lobe driver bit (part number BIT20T-2-RC3) - the correct drive bit ships with the screws so you can get to work right away without sourcing additional tooling.

Why This Product

• Built specifically for composite and PVC fascia work - unlike general-purpose screws, these fasteners carry specific approval for Trex Fascia Board attachment and are listed for PVC trim and fascia applications, so they are matched to the demands of the job rather than adapted from an unrelated use case.
• Severe-level corrosion resistance without compromise - Type 316 stainless steel is the appropriate material choice for exterior fascia exposed to moisture and weather, giving you a fastener that is engineered to last as long as the boards it secures.
• Drive system designed to reduce installation frustration - the deep T-20 6-lobe recess and included matching driver bit work together to minimize cam-outs and keep installations moving efficiently, whether you are working on a small repair or a full fascia run.
• Low-profile head design protects the fascia surface - the pancake head sits flush and resists pullover, helping to maintain the structural and visual integrity of composite and PVC fascia boards through the full life of the installation.

Frequently Asked Questions

Are these screws approved for use with Trex fascia boards?

Yes. These Simpson Strong-Tie fascia screws are specifically approved for the attachment of Trex Fascia Boards, making them a reliable choice for composite fascia installations.

What type 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 exterior applications exposed to harsh environmental conditions.

What drive type is required to install these screws?

These screws require a T-20 6-lobe (Torx-style) driver. A T-20 6-lobe driver bit (part number BIT20T-2-RC3) is included with this product. For a clean, recessed installation, the Simpson Strong-Tie Fascia Counterbore Bit (sold separately) is recommended.

What is the purpose of the low-profile pancake head design?

The low-profile pancake head is engineered to resist pullover, helping to secure fascia material firmly while allowing boards to accommodate normal expansion and contraction - resulting in a professional installation that helps prevent warping, buckling, and oil-canning.
