Simpson #7 x 2-1/4" Trim-Head Decking Screw in Red 01 with T15 6-Lobe Drive and Type 316 Stainless Steel is engineered for PVC and composite deck installations in marine or high-exposure environments where corrosion resistance and a clean, finished appearance are essential. The painted Red 01 head is designed to blend seamlessly with popular composite and PVC decking surfaces, while the Type 316 stainless steel construction stands up to saltwater, moisture, and the harsh conditions found in coastal and seaside applications. Whether you are fastening a new deck near the ocean or replacing boards in a demanding outdoor setting, these trim-head screws deliver a reliable, low-profile result that holds tight and looks great.

Key Features

• Trim-style head (0.230" diameter) - sits low and discreet on the decking surface, reducing visual distraction and producing a cleaner, more professional finished look on PVC and composite decks.
• Type 316 Stainless Steel material and finish - provides superior corrosion resistance against saltwater and harsh coastal environments, making it the right choice for marine and high-exposure outdoor installations.
• T15 6-Lobe drive - reduces driver-bit cam-out during installation, resulting in easier driving, less wasted effort, and longer bit life over the course of a project.
• Type-17 point - enables fast, clean starts in composite and PVC decking materials without the need for pre-drilling in most field conditions, speeding up installation.
• Coarse threads - draw decking boards and other materials tightly down to the framing, creating a firm, secure connection that resists movement and surface gaps.
• Red 01 painted head - color-matched to blend with major PVC and composite decking brands, helping fasteners virtually disappear into the deck surface for a polished result.
• Available in 13 head colors - gives installers flexibility to match a wide variety of decking colors and manufacturers without mismatched fastener heads.

Why This Product

• Built for marine and coastal environments - Type 316 stainless steel offers the highest level of corrosion resistance among standard stainless grades, making these screws specifically suited to seaside decks and high-humidity outdoor installations where standard fasteners would fail prematurely.
• Color-matched for a finished appearance - the Red 01 painted trim head is designed to blend with major PVC and composite decking products, so the fasteners recede into the surface rather than drawing the eye - a key advantage for high-end deck finishing work.
• Driver-bit efficiency on the job - the 6-lobe T15 drive reduces cam-out, which translates directly into less bit replacement, faster driving, and reduced installer fatigue across a full deck installation.
• Purpose-built for composite and PVC decking - the combination of trim head profile, Type-17 point, and coarse threads is specifically optimized for synthetic decking materials, delivering the holding power and appearance that composite deck installations demand.

Frequently Asked Questions

What types of decking are these screws designed for?

These trim-head screws are specifically designed for PVC and composite deck installations. The trim-head profile, Type-17 point, and coarse threads work together to create a clean, secure fastening result in synthetic decking materials commonly used in residential and commercial outdoor construction.

Why is Type 316 stainless steel recommended for decking applications?

Type 316 stainless steel provides superior corrosion resistance compared to standard grades, making it especially well suited for marine environments, seaside installations, and any high-exposure outdoor application where moisture, salt air, or chemicals are present. It helps ensure the fasteners maintain their integrity and holding power over the long term.

What does the T15 6-Lobe drive offer compared to a standard drive type?

The T15 6-Lobe drive is engineered to reduce cam-out during driving. This means the driver bit stays engaged more reliably in the screw head, resulting in easier installation, less wear on the bit, and a cleaner drive overall - particularly useful when installing a large number of fasteners across a full deck surface.

Is predrilling required when using these trim-head screws near board ends?

Predrilling is recommended near board ends to help prevent splitting. The Type-17 point supports fast starts in most field conditions, but taking the precaution of predrilling at board ends protects the integrity of the decking material and helps achieve the best possible finished result.
