Simpson #7 x 2-1/4" Tan Trim-Head Screw with T15 6-Lobe Drive in Type 316 Stainless Steel is engineered for PVC and composite deck installations in demanding outdoor environments. The low-profile trim head blends discreetly into decking surfaces, while the Type 316 stainless steel construction delivers exceptional corrosion resistance in marine, coastal, and high-moisture applications. Available with a painted tan head that coordinates with popular composite and PVC decking products, this fastener combines a clean, finished appearance with the long-term durability required in high-exposure conditions.

Key Features

• Trim-style head design - the low-profile 0.230" head diameter sits unobtrusively on the deck surface, creating a cleaner, more finished appearance than standard screw heads on composite and PVC boards
• Type 316 stainless steel material and finish - provides superior corrosion resistance compared to standard stainless grades, making it well-suited for seaside, marine, and other high-exposure environments where moisture and salt are persistent concerns
• T15 6-lobe drive - the six-lobe engagement geometry reduces driver bit cam-out during installation, resulting in easier driving, less stripped fasteners, and extended bit life on large projects
• Type-17 cutting point - the self-starting point bites into material quickly for fast, accurate starts without pre-drilling in most field conditions
• Coarse threads - pull the decking board tightly and securely against the framing, reducing gaps and movement at the fastener point for a stable, long-lasting deck surface
• Tan painted head - color-matched to blend with popular tan-toned PVC and composite decking products, minimizing the visual impact of each fastener on the finished deck

Why This Product

• Designed specifically for PVC and composite deck installations where conventional fasteners may corrode prematurely - the Type 316 stainless steel construction holds up in marine and coastal environments where lesser alloys fail
• The trim head and tan painted finish work together to produce a polished, professional result on decking surfaces - the head diameter of 0.230" keeps the fastener unobtrusive while still providing solid holding power
• The T15 6-lobe drive reduces installation fatigue and tool wear on large decking jobs, where cam-out with standard drive styles can slow progress and damage both fasteners and driver bits
• The Type-17 point and coarse thread combination streamlines the fastening process - the point starts quickly and the threads draw boards down firmly, reducing the need for extra passes or adjustments during installation

Frequently Asked Questions

What type of decking is this screw designed for?

This trim-head screw is designed for use with PVC and composite deck boards. The low-profile trim head and painted tan finish are specifically intended to blend with the surface of these decking materials for a clean, finished look.

Why choose Type 316 stainless steel for deck fasteners?

Type 316 stainless steel offers superior corrosion resistance compared to other stainless grades, making it the right choice for marine environments, coastal installations, and any high-exposure outdoor application where moisture, salt air, or harsh conditions are present. The marketing guidance from Simpson recommends Type 316 specifically for seaside applications.

Is pre-drilling required when installing these screws?

The Type-17 point is designed for fast starts, which reduces the need for pre-drilling in most situations. However, pre-drilling is recommended near board ends to help prevent splitting, particularly with certain composite or PVC materials.

What drive bit is needed for these screws?

These screws use a T15 6-lobe drive. The 6-lobe geometry is designed to reduce cam-out during driving, which helps preserve the driver bit and makes installation faster and more consistent compared to standard drive styles.
