Simpson Trim-Head Decking Screws in #7 x 2-1/4" with T15 6-Lobe Drive are engineered for PVC and composite deck installations where a clean, low-profile fastening result matters. Finished in Type 316 Stainless Steel with a painted Gray 03 head, these screws deliver superior corrosion resistance in demanding coastal, marine, and high-moisture outdoor environments - making them a go-to choice for seaside decking projects where long-term durability is non-negotiable. The trim-style head blends discreetly into the decking surface, and matching painted heads are available in 13 colors to coordinate with most major composite and PVC decking brands.

Key Features

• Trim Head Design (0.230" head diameter) - the small, low-profile head sits flush and nearly disappears into the decking surface for a cleaner, more finished appearance compared to standard screw heads
• Type 316 Stainless Steel Material and Finish - provides superior corrosion resistance against saltwater, moisture, and harsh outdoor conditions, making these screws well-suited for marine and high-exposure applications
• Gray 03 Painted Head - color-matched to blend with popular PVC and composite decking products, reducing the visual impact of fasteners on the finished deck surface
• T15 6-Lobe Drive - the six-lobe (star-drive) interface reduces driver-bit cam-out during installation, resulting in easier, faster driving and extended bit life over long projects
• Type-17 Point - aggressive point geometry allows the screw to start quickly and drill into material cleanly without the need for pre-boring in most applications, speeding up installation
• Coarse Thread Pattern - draws decking boards and composite material tightly against the framing, minimizing gaps and creating a secure, stable connection
• #7 x 2-1/4" Size - properly sized for fastening typical PVC and composite deck boards to standard framing members with the appropriate penetration depth

Why This Product

• Built for coastal and marine decking projects - Type 316 Stainless Steel is the preferred material for seaside and high-exposure environments where standard stainless or coated fasteners may corrode prematurely, protecting your deck structure over time
• Designed to disappear into your deck surface - the trim head profile and Gray 03 painted finish work together to minimize the visual footprint of each fastener, keeping the focus on the decking material itself rather than the hardware
• Reduces installation fatigue and bit waste - the T15 6-Lobe drive geometry virtually eliminates cam-out, so installers spend less time fighting the driver and replacing worn bits during large deck projects
• Compatible with most major PVC and composite decking brands - with painted heads available in 13 colors, these screws are engineered to blend with the industry's most widely used decking products, making color-matching straightforward

Frequently Asked Questions

Are these screws appropriate for use near saltwater or in marine environments?

Yes. These screws are made from Type 316 Stainless Steel, which is specifically recommended for seaside applications and environments with high moisture or salt exposure. Type 316 offers superior corrosion resistance compared to other stainless grades, making it a reliable choice for coastal and marine decking installations.

What type of decking material are these screws designed for?

These Trim-Head screws are designed for use with PVC and composite deck boards. The trim-style head profile and painted color options are specifically intended to blend with the surface of composite and PVC decking products from most major manufacturers.

Should I pre-drill near the ends of deck boards before driving these screws?

Predrilling is recommended near board ends to prevent splitting, particularly when working close to the edge of a deck board. This extra step helps protect the material and ensures a clean installation result.

What driver bit do these screws require?

These screws use a T15 6-Lobe (star-drive) bit. The 6-lobe drive interface is designed to minimize cam-out during driving, which helps protect both the screw head and the driver bit - especially useful during extended installation sessions on larger deck projects.
