Simpson #7 x 2-1/4" Trim-Head Decking Screw with T15 6-Lobe Drive in Type 316 Stainless Steel (Tan 01) is engineered for fastening PVC and composite decking in marine, coastal, and high-moisture environments where ordinary fasteners fail. The low-profile trim head sits flush and discreet against the decking surface, while the Tan 01 painted finish blends seamlessly with most major composite and PVC decking brands. Built from Type 316 stainless steel, these screws deliver outstanding corrosion resistance in saltwater-exposed and chemically demanding outdoor settings.

Key Features

• Trim-style head (0.230" diameter) - sits low and unobtrusive on the decking surface for a cleaner, more finished appearance compared to standard hex or bugle heads
• Type 316 Stainless Steel material and finish - resists saltwater, chlorides, and harsh outdoor exposure, making these screws the right choice for seaside, marina, and high-humidity installations
• Tan 01 painted head - color-matched to blend with popular PVC and composite decking brands, reducing the visibility of fasteners for a professional, seamless look
• T15 6-Lobe (6-lobe) drive type - minimizes driver-bit cam-out during installation, resulting in easier, faster driving and extended bit life on the job
• Type-17 point - self-starting tip cuts into material quickly for fast, clean starts without pre-drilling through the main field, reducing installation time
• Coarse thread pattern - draws decking boards and substrate tightly together against the framing, creating a secure, gap-free connection
• #7 screw size at 2-1/4" length - sized to properly penetrate PVC and composite deck boards while reaching securely into the framing below
• Approximately 138 screws per pound - allows accurate quantity estimation before starting a project, reducing waste and over-ordering

Why This Product

• Designed specifically for coastal and marine deck installations - Type 316 stainless steel provides a higher level of corrosion resistance than Type 304 or zinc-coated alternatives, making it the appropriate fastener choice where saltwater spray, salt air, or persistent moisture are present.
• Achieves a cleaner finished appearance on composite and PVC decks - the trim head's reduced diameter and Tan 01 color coating work together to minimize fastener visibility, which is a common requirement on high-end residential and commercial deck projects.
• Reduces installation frustration and bit waste - the 6-lobe drive geometry holds the bit securely during driving, preventing the stripping and cam-out that slows work and consumes driver bits when using standard Phillips or square drives.
• Available in a color matched to popular decking brands - with Tan 01 among 13 available head colors, contractors and homeowners can match fasteners to their specific decking product rather than settling for a mismatched metallic finish.

Frequently Asked Questions

What type of decking material are these screws designed for?

These trim-head screws are designed for use with PVC and composite decking. The Tan 01 painted head is color-matched to blend with most major PVC and composite decking manufacturers, and the Type 316 stainless steel construction handles the moisture exposure common in these deck installations.

Why should I choose Type 316 stainless steel over other finishes for my deck screws?

Type 316 stainless steel provides superior corrosion resistance compared to standard stainless alloys, making it the appropriate choice for marine environments, seaside applications, and any high-exposure outdoor setting where saltwater, salt air, or persistent moisture could degrade a lesser finish.

Is pre-drilling required when using these screws?

The Type-17 point allows for fast starts without pre-drilling through most of the field. However, pre-drilling is recommended near board ends to help prevent splitting of the decking material.

What driver bit do I need for the T15 6-Lobe drive?

These screws require a T15 6-lobe (Torx-style) driver bit. The 6-lobe drive is designed to reduce cam-out compared to Phillips or square drives, which results in easier driving and longer bit life during installation.
