Simpson Trim-Head Decking Screws in #7 x 1-5/8" with T15 6-Lobe Drive and Type 316 Stainless Steel finish are engineered for PVC and composite deck installations in marine, coastal, and high-exposure environments where superior corrosion resistance is critical. The Brown 01 painted head is matched to blend seamlessly with major composite and PVC decking brands, delivering a cleaner, more finished appearance on the deck surface. Whether you're working on a seaside boardwalk or a backyard composite deck, these trim-head fasteners combine long-term durability with a low-profile aesthetic that keeps the focus on the decking - not the hardware.

Key Features

• Trim Head design with 0.230" head diameter - the low-profile head sits flush and discreet on composite or PVC decking surfaces, reducing the visual footprint of each fastener for a polished finish.
• Type 316 Stainless Steel material and finish - provides superior resistance to saltwater, chlorides, and harsh outdoor weathering, making these screws the right choice for coastal and marine deck applications.
• Brown 01 painted head color - blends with the decking surface to make fastener heads nearly invisible, available in 13 colors matched to most major PVC and composite decking manufacturers.
• T15 6-Lobe (6-lobe) drive type - reduces driver-bit cam-out during installation, resulting in smoother driving, fewer stripped heads, and longer bit life on the job.
• Type-17 Point - self-starting point design allows for fast, clean starts without pre-drilling in most field applications, saving installation time.
• Coarse thread pattern - threads on approximately two-thirds of the shank draw the decking board tightly against the framing for a secure, rattle-free connection.
• #7 screw size at 1-5/8" length - proportioned for reliable fastening of PVC and composite decking boards to standard framing members without over-penetration.
• Approximately 195 screws per pound - a consistent count-per-weight ratio helps estimators and contractors plan material quantities accurately before the job begins.

Why This Product

• Purpose-built for marine and high-exposure deck environments - Type 316 Stainless Steel is the preferred material for coastal and saltwater-adjacent installations where standard fasteners corrode prematurely, making these screws a reliable long-term solution for demanding conditions.
• Color-matched for a professional finish - the Brown 01 painted head is engineered to blend with the surrounding deck surface rather than stand out against it, delivering the clean, finished look that composite and PVC deck installations require.
• Drives faster and cleaner with less effort - the combination of the Type-17 self-starting point and 6-lobe drive minimizes cam-out and slipping, reducing driver wear and installer fatigue over the course of a full deck installation.
• Designed specifically for PVC and composite decking compatibility - the trim head profile and coarse thread pattern work together to seat flush in softer composite and PVC materials without mushrooming the surface or leaving raised fastener heads.

Frequently Asked Questions

Are these screws suitable for use near saltwater or in coastal environments?

Yes. These screws are made from Type 316 Stainless Steel, which offers superior corrosion resistance in marine and high-exposure environments. Simpson specifically recommends Type 316 for seaside applications where standard stainless or coated fasteners may degrade more quickly.

Do I need to pre-drill before driving these screws?

The Type-17 Point is designed for fast, self-starting installation in most applications. However, pre-drilling is recommended near board ends to help prevent splitting of the decking material.

What drive bit do I need to install these screws?

These screws use a T15 6-Lobe drive. A T15 6-lobe (Torx-style) driver bit is required for installation. The 6-lobe design helps prevent cam-out and extends bit life compared to traditional Phillips-head fasteners.

Will the Brown 01 head color match my composite or PVC decking?

The Brown 01 color is one of 13 available painted head colors engineered to blend with most major PVC and composite decking manufacturers. Note that actual product colors may vary from colors shown on your monitor - verify the color match with a physical sample when color accuracy is critical.
