Simpson Trim-Head Decking Screw - #7 x 2-1/4", White 01, T15 6-Lobe Drive, Type 305 Stainless Steel by Simpson delivers a clean, nearly invisible fastening solution for PVC and composite deck installations in demanding outdoor and marine environments. The low-profile trim head sits flush and discreet against the decking surface, while the White 01 painted head blends seamlessly with light-colored decking boards. Type 305 stainless steel construction provides superior corrosion resistance, making these screws a reliable choice for high-exposure settings where standard fasteners would degrade. Whether you are fastening composite boards in a coastal yard or finishing a PVC deck in a high-moisture zone, this screw is engineered to hold tight and look great over the long term.

Key Features

• Trim head design with 0.230" head diameter - the low-profile head sits flush and stays visually subtle on the decking surface, delivering a clean, professional finish without unsightly fastener heads dominating the look of the deck.
• Type 305 stainless steel material and finish - resists corrosion in marine, coastal, and high-moisture outdoor environments where standard steel fasteners would rust and stain surrounding decking materials.
• White 01 painted head - color-matched to blend with light-toned PVC and composite decking from most major manufacturers, reducing the visual impact of each fastener and creating a cohesive finished appearance.
• T15 6-lobe drive - the six-lobe interface maximizes contact between driver bit and fastener head, helping prevent cam-out during installation for easier, faster driving and extended driver bit life.
• Type-17 point - the self-drilling point bites into material quickly without pre-spinning, allowing fast, confident starts that reduce installation time on composite and PVC decking surfaces.
• Coarse thread type - aggressive coarse threads pull decking boards tightly down to the framing, creating a firm, rattle-free connection that stays secure through seasonal movement and heavy foot traffic.
• #7 x 2-1/4" size - the screw diameter and length are sized appropriately for typical composite and PVC decking board thickness, providing solid holding power without over-penetrating the framing below.

Why This Product

• Built for corrosion-prone environments - Type 305 stainless steel construction is specifically suited to marine settings, waterfront properties, and other high-exposure outdoor applications where moisture and salt air accelerate fastener failure on ordinary screws.
• Designed to disappear into your deck - the combination of a trim-profile head and a White 01 color-matched painted finish means these fasteners blend with light-toned composite or PVC decking boards rather than drawing the eye, resulting in a cleaner, more polished deck surface.
• Reduces installer fatigue and bit waste - the T15 6-lobe drive geometry reduces cam-out, so installers spend less time repositioning bits and replacing stripped fasteners, keeping the job moving efficiently across large deck areas.
• Versatile color availability means one fastener family fits many projects - with painted heads available in 13 colors matched to most major PVC and composite decking manufacturers, these Simpson trim-head screws can be coordinated across different deck board colors and brands on the same project or across multiple jobs.

Frequently Asked Questions

What types of decking are these screws designed for?

These Simpson trim-head screws are designed for use with PVC and composite decking installations. The trim head profile and color-matched painted heads are engineered to blend with most major PVC and composite decking manufacturers, making them a practical choice for both residential and marine deck projects.

Why choose Type 305 stainless steel for outdoor decking fasteners?

Type 305 stainless steel provides superior corrosion resistance compared to standard plated or galvanized fasteners, making it well suited to marine settings, coastal properties, and other high-exposure outdoor environments where moisture, humidity, and salt air are ongoing concerns. This material choice helps ensure the fasteners maintain their structural integrity and appearance over time.

Is pre-drilling required before driving these screws?

The Type-17 point is designed for fast starts and efficient penetration into composite and PVC decking materials. However, pre-drilling is recommended near board ends to help prevent splitting, particularly when working close to the edge of a board where material is most vulnerable to stress cracking.

What driver bit is needed for the T15 6-Lobe drive?

These screws use a T15 6-lobe drive, which requires a T15 Torx-compatible driver bit. The 6-lobe interface is designed to reduce cam-out during driving, so using the correct T15 bit is important for maximizing contact, protecting the screw head, and extending bit life over the course of a large installation.
