Simpson #8 x 1 3/4 Gray 04 Composite Fascia Screws in Type 316 Stainless Steel are specialty fasteners engineered for the secure attachment of PVC and composite fascia boards, including Trex fascia. Built from Type 316 stainless steel for severe-level corrosion resistance and designed with a low-profile pancake head that resists pullover, these screws deliver a clean, professional finish that holds up in demanding outdoor environments where standard fasteners fall short.

Key Features

• Approved for attachment of Trex Fascia Boards - gives installers a manufacturer-recognized fastener for composite fascia work, reducing guesswork and liability on the job.
• Deep T-20 6-lobe recess - reduces cam-outs during installation for faster, cleaner driving with fewer stripped recesses (compatible bit part number: BIT20T-2-RC3).
• Type-17 point - cuts into the board quickly for fast starts without pre-drilling, saving time on large fascia runs.
• Low-profile pancake head - resists pullover and sits flush against the board surface for a refined, finished appearance with no raised edges.
• Type 316 stainless steel construction - provides severe-level corrosion resistance, making these screws well-suited for coastal, high-humidity, and other harsh outdoor environments.
• Gray 04 head color - blends with fascia board surfaces for a cleaner look that minimizes the visibility of fastener heads after installation.
• Coarse thread design - bites firmly into PVC and composite fascia material to maintain a secure, stable hold over time.

Why This Product

• Built for composite and PVC fascia from the ground up - unlike general-purpose screws, these fasteners are specifically engineered for PVC trim and composite fascia board applications, including approved use with Trex fascia, so the fit, finish, and holding power are dialed in for the material.
• Severe-level corrosion resistance where it matters most - Type 316 stainless steel stands up to the moisture, salt air, and chemical exposure that breaks down lesser fasteners, making these a reliable long-term choice for exterior fascia installations.
• Designed to drive cleanly and consistently - the combination of the Type-17 tip for fast starts and the deep T-20 6-lobe recess to reduce cam-outs means fewer frustrating interruptions and a smoother workflow, whether you are installing a single board or running an entire project.
• Color-matched for a professional finish - the Gray 04 pancake head keeps fasteners from drawing the eye, complementing the fascia surface and contributing to the polished appearance that composite and PVC trim installations demand.

Frequently Asked Questions

Are these screws approved for use with Trex fascia boards?

Yes. These fascia screws are specifically approved for the attachment of Trex Fascia Boards, making them a trusted 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 demanding outdoor and coastal environments.

What drive type is required for these screws?

These screws use a deep T-20 6-lobe recess designed to reduce cam-outs. A T-20 6-lobe driver bit (part number BIT20T-2-RC3) is included with the package.

Why is the pancake head design beneficial for fascia installations?

The low-profile pancake head resists pullover, helping to create a clean, professional installation that prevents issues such as warping, buckling, and oil-canning as fascia boards expand and contract with environmental conditions.
