Simpson #7 x 2-1/4" Trim-Head Decking Screw in Tan 03 with T15 6-Lobe Drive and Type 305 Stainless Steel is engineered for clean, low-profile fastening on composite and PVC deck boards in demanding outdoor and marine environments. From Simpson, a trusted name in structural fastening, these stainless steel trim-head screws deliver superior corrosion resistance alongside a refined surface finish - making them a go-to choice for dock construction, boardwalks, and residential or commercial deck installations where appearance and longevity both matter.

Key Features

• Trim-Head design with 0.230" head diameter - sits low and discreet on the decking surface for a clean, professional finish that minimizes the visual footprint of each fastener
• Type 305 Stainless Steel construction - provides superior corrosion resistance in marine, high-exposure, and wet outdoor environments where standard coated fasteners would fail prematurely
• Tan 03 painted head color - blends with most major PVC and composite decking products, creating a color-matched, nearly invisible fastener appearance across 13 available color options
• T15 6-Lobe (6-lobe) drive system - reduces driver-bit cam-out during installation, resulting in faster, easier driving and significantly longer bit life compared to traditional Phillips or square drives
• Type-17 point - enables fast, self-starting penetration into composite and wood decking without the need for pre-drilling in most field conditions, speeding up installation
• Coarse thread pattern - draws decking boards and substrate materials tightly together against the framing, creating a firm, rattle-free connection that holds over time
• 2-1/4" length (#7 screw size) - sized appropriately for composite and wood deck board fastening applications, providing adequate embedment into the framing below
• Approximately 138 screws per pound - gives installers a reliable count for estimating quantities needed per project without guesswork

Why This Product

• Built for corrosive environments - Type 305 Stainless Steel construction makes these screws the right choice for dock, boardwalk, and marine deck applications where moisture, salt air, and humidity accelerate rust and fastener failure in lesser materials
• Engineered for composite and PVC decking - the trim-head profile and Tan 03 color-matched painted head are specifically designed to blend with major composite and PVC decking brands, delivering a finished look that surface-mount screws simply cannot match
• Faster installation with fewer stripped drives - the T15 6-lobe drive system paired with the Type-17 self-starting point means less bit slippage, fewer stripped fasteners, and a more efficient installation process for contractors and DIYers alike
• Reliable hold in wood and composite deck boards - the coarse thread configuration locks the deck board tightly to the joist framing, reducing board movement, squeaking, and long-term fastener loosening in outdoor deck and boardwalk structures

Frequently Asked Questions

Are these screws suitable for use in marine or seaside environments?

Yes. These screws are made from Type 305 Stainless Steel, which provides superior corrosion resistance in marine and high-exposure environments. They are specifically noted as appropriate for use where PVC or composite decks are installed in areas with elevated moisture or salt air exposure. For the most demanding seaside applications, Type 316 stainless steel is generally recommended.

What decking materials are these trim-head screws compatible with?

These screws are approved for use with composite deck boards, wood deck boards, and dock and boardwalk construction. The Tan 03 painted head color is designed to blend with most major PVC and composite decking manufacturers, and heads are available in 13 colors total to match a wide range of decking products.

What drive bit do I need to install these screws?

These screws use a T15 6-Lobe drive system. A T15 6-lobe (also referred to as a 6-lobe or Torx-style) driver bit is required for installation. This drive type is specifically designed to reduce cam-out during driving, which extends bit life and makes installation faster and more controlled.

Do I need to pre-drill before installing these screws near board ends?

While the Type-17 point is designed for fast, self-starting penetration, pre-drilling is recommended near board ends to help prevent splitting - particularly in wood deck board applications. The coarse thread design helps draw boards tightly to framing, so proper placement and technique will support the best results.
