Simpson #7 x 2-1/4" Trim-Head Decking Screw with T15 6-Lobe Drive in Type 316 Stainless Steel is engineered for fastening PVC and composite decking in demanding outdoor and coastal environments. Featuring a Tan 03 painted head designed to blend seamlessly with popular decking surfaces, this screw delivers a clean, low-profile finish while offering the superior corrosion resistance required for marine, seaside, and high-exposure applications. The combination of Type 316 stainless steel construction and a specialized trim-style head makes these fasteners a trusted choice for contractors and builders who need both durability and aesthetics in exterior deck installations.

Key Features

• Trim Head Design (0.230" head diameter) - sits flush and discreet on the decking surface, minimizing visual interruption for a polished, professional finish on PVC and composite boards.
• Type 316 Stainless Steel material and finish - provides superior corrosion resistance in saltwater, marine, and high-humidity environments where standard fasteners would degrade prematurely.
• T15 6-Lobe Drive - reduces driver-bit cam-out during installation, allowing for faster, cleaner driving and extending the usable life of your driver bits.
• Type-17 Point - enables fast, reliable starts without pre-drilling in most applications, saving installation time and effort.
• Coarse Threads - draw decking boards and other materials tightly against the framing for a secure, snug connection that resists movement over time.
• Tan 03 painted head - matched to coordinate with most major PVC and composite decking manufacturers, helping installed screws disappear into the deck surface for a finished look.
• Available in 13 painted head colors - allows color-matching across a wide range of popular decking products, reducing the need for additional finishing steps on visible fastener heads.

Why This Product

• Built for coastal and marine decks - Type 316 stainless steel is the recommended choice for seaside and saltwater-adjacent installations where corrosion resistance is critical to long-term fastener integrity.
• Designed specifically for PVC and composite decking - the trim head profile and Tan 03 color-matched paint work together to create a cleaner, more finished appearance on modern synthetic decking surfaces.
• Reduces installation fatigue and bit wear - the T15 6-Lobe drive system minimizes cam-out, meaning fewer stripped heads, less rework, and longer-lasting driver bits on the job site.
• Screw size and length chosen for reliable deck fastening - the #7 gauge and 2-1/4" length provide the penetration and holding strength needed to pull decking boards firmly down to the substructure framing.

Frequently Asked Questions

What type of decking is this screw designed for?

This trim-head screw is designed for use with PVC and composite decking materials. The Tan 03 painted head is color-matched to blend with most major PVC and composite decking manufacturers, and the Type 316 stainless steel construction provides the corrosion resistance needed in outdoor and high-exposure environments where these materials are commonly installed.

Why should I choose Type 316 stainless steel for my deck project?

Type 316 stainless steel offers superior corrosion resistance compared to standard fastener materials, making it the preferred choice for marine environments, seaside applications, and other high-exposure locations where moisture, salt air, and the elements can cause ordinary screws to corrode and fail over time.

Is pre-drilling required when installing these screws?

The Type-17 point is designed for fast starts and can often be driven without pre-drilling. However, pre-drilling is recommended near board ends to help prevent splitting of the decking material.

What driver bit is needed to install these screws?

These screws use a T15 6-Lobe drive. This drive style is specifically designed to reduce cam-out during driving, which helps protect both the screw head and your driver bit, resulting in easier installation and longer bit life.
