Simpson #8 x 1 3/4 Tan 01 Composite Fascia Screws in Type 316 Stainless Steel are purpose-built fasteners engineered for clean, professional attachment of composite and PVC fascia boards. Approved for use with Trex Fascia Boards, these screws pair a low-profile pancake head with a Type-17 point and deep T-20 6-lobe drive to deliver fast, cam-out-resistant installation with a finished appearance that holds up in demanding exterior conditions.

Key Features

• Approved for attachment of Trex Fascia Boards - gives you a manufacturer-approved, code-compliant installation on one of the most widely used composite fascia products available.
• Deep T-20 6-lobe recess drive - significantly reduces cam-outs during driving, protecting both the screw head and your fascia surface for a cleaner finished result.
• Type-17 point - bores into material quickly for fast starts without pre-drilling, saving time across large fascia runs.
• Low-profile pancake head - resists pullover and sits flush against the fascia surface, minimizing the visual footprint of each fastener.
• Type 316 stainless steel construction - provides severe-level corrosion resistance, making these screws well-suited for coastal environments, high-moisture exposures, and long-term exterior use.
• Tan 01 head color - blends with the fascia surface for a more discreet, finished appearance compared to standard silver fasteners.
• Includes T-20 6-lobe driver bit - comes ready to use out of the box so you can get started without sourcing a separate bit.

Why This Product

• Specifically engineered for fascia work - unlike general-purpose screws, these are designed from the head profile to the point type with composite and PVC fascia board installation in mind, reducing the risk of surface damage, pullover, or splitting.
• Trex-approved for added confidence - the explicit approval for attachment of Trex Fascia Boards means installers can proceed knowing the fastener meets the material manufacturer's own requirements, not just general-use specs.
• Severe-level corrosion resistance for long-term exterior performance - Type 316 stainless steel goes beyond standard corrosion protection, making these screws a reliable choice for projects in harsh or high-humidity environments where fastener failure is a real concern.
• Drive system designed to protect your work - the deep T-20 6-lobe recess that reduces cam-outs is not a minor convenience; on a visible fascia surface, cam-out damage to screw heads or surrounding material is difficult to conceal, and this feature directly reduces that risk.

Frequently Asked Questions

What type of stainless steel are these fascia screws made from, and why does it matter?

These screws are made from Type 316 stainless steel, which provides severe-level corrosion resistance. This makes them an excellent choice for exterior fascia applications where exposure to moisture, salt air, or harsh weather conditions is a concern.

Are these screws approved for use with Trex fascia boards?

Yes. The Simpson T08175FS75TN01 fascia screw is specifically approved for the attachment of Trex Fascia Boards, ensuring a code-compliant and manufacturer-approved installation.

What drive type does this screw use, and what bit do I need?

This screw uses a deep T-20 6-lobe recess drive, which is engineered to reduce cam-outs during installation. A T-20 6-lobe driver bit (part number BIT20T-2-RC3) is included with the screws. The Simpson Strong-Tie Fascia Counterbore Bit (FSBIT, sold separately) is also recommended for a proper countersunk installation.

Why is a pancake head used on these fascia screws?

The low-profile pancake head is specifically designed to resist pullover, keeping the fascia board securely fastened while allowing the material to expand and contract naturally. This helps prevent warping, buckling, and oil-canning for a clean, professional finish.
