Simpson #8 x 1 3/4 Gray 01 Composite Fascia Screws in Type 316 Stainless Steel are purpose-built fasteners designed for the secure attachment of PVC trim, composite fascia boards, and specialty applications where a clean, professional finish and long-term durability are non-negotiable. Engineered by Simpson with a low-profile pancake head, a Type-17 point, and severe-level corrosion resistance, these screws deliver confident performance in demanding outdoor environments where lesser fasteners would corrode, strip, or fail.

Key Features

• Approved for attachment of Trex Fascia Boards - gives contractors and DIYers confidence that these screws meet the specific requirements of a leading composite fascia product, eliminating guesswork on compatibility.
• Deep T-20 6-lobe recess - reduces cam-outs during driving, protecting both the screw head and the fascia board surface for a cleaner, faster installation (compatible bit part number: BIT20T-2-RC3).
• Type-17 point - bores into material quickly for fast starts without pre-drilling, saving time on the job.
• Low-profile pancake head - resists pullover and sits flush against the board surface, producing a finished look with no raised edges or surface damage.
• Type 316 stainless steel construction - provides severe-level corrosion resistance, making these screws well-suited for coastal, high-moisture, and other harsh outdoor environments.
• Gray 01 head color - blends with composite and PVC fascia materials for a discreet, professional appearance once installed.

Why This Product

• Trex-approved for composite fascia installations - these screws carry specific approval for Trex fascia board attachment, making them a trusted, code-conscious choice for composite exterior projects rather than a generic substitute.
• Built for severe-exposure environments - Type 316 stainless steel goes beyond standard corrosion resistance, holding up in coastal and high-humidity conditions where ordinary stainless or coated fasteners break down over time.
• Engineered to reduce installation errors - the combination of a deep T-20 6-lobe recess that minimizes cam-outs and a Type-17 tip that speeds up starts means fewer damaged screw heads, fewer surface defects, and a more consistent finish across the entire fascia run.
• Color-matched head for a refined result - the Gray 01 pancake head is designed to complement composite and PVC fascia materials, so the fastener recedes visually into the board and keeps the focus on the finished surface, not the hardware.
