Simpson Trim-Head Decking Screw, #7 x 2-1/4", White 01, T15 6-Lobe Drive, Type 316 Stainless Steel by Simpson delivers a clean, low-profile finish on PVC and composite deck surfaces while providing the superior corrosion resistance demanded by marine and high-exposure outdoor environments. The painted White 01 head blends seamlessly with light-colored decking materials, giving finished deck surfaces a polished, professional appearance without exposed metal distracting from the overall look. Designed specifically for coastal and high-moisture applications, this trim-head fastener combines the toughness of 316 stainless steel with a refined head geometry that virtually disappears into the deck surface.

Key Features

• Trim-head design with 0.230" head diameter - sits low and flush against the decking surface, minimizing visual impact and delivering a clean, finished look on PVC and composite boards
• Type 316 Stainless Steel material - provides superior corrosion resistance in saltwater, marine, and other high-exposure environments where standard stainless or coated screws may fail prematurely
• T15 6-Lobe drive - reduces driver-bit cam-out during installation, allowing for easier, faster driving and significantly longer bit life compared to standard Phillips or square drives
• Type-17 point - enables fast, clean starts without pre-drilling in most applications, speeding up installation and reducing worker fatigue
• Coarse thread pattern - draws decking boards and other material tightly and securely against framing for a firm, rattle-free connection
• White 01 painted head - color-matched to blend with major PVC and composite decking manufacturers, keeping the deck surface looking intentional and uniform rather than patched or mismatched
• Available in 13 painted head colors - offers broad compatibility across most major composite and PVC decking color lines, reducing the need for custom color solutions

Why This Product

• Built for marine and coastal decking: Type 316 stainless steel is the material of choice for seaside and high-moisture environments - it withstands saltwater exposure and harsh outdoor conditions where lesser fasteners corrode and stain the deck surface over time.
• Disappears into the deck surface: The trim-head geometry and White 01 color-matched painted head work together to create a near-invisible fastener profile on compatible light-colored composite or PVC decking, maintaining the clean aesthetic the installer intended.
• Faster installation with fewer frustrations: The Type-17 point starts quickly without slipping, and the T15 6-lobe drive keeps the bit engaged and reduces cam-out - meaning fewer stripped screw heads, less rework, and a smoother installation experience.
• Engineered specifically for PVC and composite decks: From the head size and color options to the coarse thread geometry that pulls boards tight to framing, every design element of this screw is tailored to the materials and expectations of modern composite and PVC deck construction.

Frequently Asked Questions

What types of decking is this screw designed for?

This trim-head screw is designed for use with PVC and composite decking materials. The small trim-head profile and painted head colors are specifically matched to blend with most major PVC and composite decking manufacturers, making it ideal for those installations in marine or high-exposure outdoor environments.

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

Type 316 stainless steel offers superior corrosion resistance compared to standard stainless grades, making it the recommended choice for seaside applications, coastal environments, and any high-exposure setting where moisture, salt air, or chemicals are a concern. It helps prevent fastener degradation and the staining that corroded hardware can leave on decking surfaces.

Do I need to pre-drill before driving these screws?

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

What driver bit do I need for the T15 6-Lobe drive?

These screws use a T15 6-lobe (Torx-style) drive. A T15 driver bit is required. The 6-lobe design helps prevent cam-out during driving, which extends bit life and makes installation easier compared to Phillips or square-drive alternatives.
