Simpson Trim-Head Decking Screw, #7 x 2-1/4", Tan 04, 6-Lobe Drive, Type 305 Stainless Steel by Simpson is engineered for PVC and composite deck installations where a clean, low-profile fastening solution is required alongside reliable corrosion resistance. The trim-style head blends discreetly into the decking surface, while the Type 305 stainless steel construction delivers the durability needed for marine and high-exposure outdoor environments. With a painted Tan 04 head matched to complement most major composite and PVC decking brands, these screws combine functional performance with a polished, finished appearance.

Key Features

• Trim Head design with 0.230" head diameter - sits flush and low-profile against the decking surface for a neat, clean finish that minimizes visual interruption on composite and PVC boards
• Type 305 Stainless Steel material and finish - provides superior corrosion resistance in marine environments, high-moisture areas, and other demanding outdoor exposures where standard fasteners would degrade
• Tan 04 painted head color - blends with most major PVC and composite decking manufacturers' board colors, reducing the visibility of fasteners for a professional, finished look
• T15 6-Lobe drive type - reduces cam-out during driving, resulting in less bit slippage, easier installation, and extended bit life compared to traditional drive styles
• Type-17 point - enables fast, clean starts without pre-drilling in most applications, speeding up installation and reducing prep time
• Coarse threads - draw decking boards tightly to the framing, creating a secure, stable connection that resists movement and gaps over time
• #7 screw size, 2-1/4" length - sized appropriately for composite and PVC deck board applications, balancing holding strength with clean fastener penetration

Why This Product

• Built for corrosive environments - Type 305 stainless steel construction holds up in marine settings and high-exposure outdoor conditions where standard fasteners rust and fail, making this screw a dependable choice for coastal or waterfront deck projects.
• Engineered for composite and PVC decking compatibility - the trim head profile and color-matched Tan 04 painted finish are specifically designed to suit the aesthetics and surface requirements of today's composite and PVC decking products.
• Faster, cleaner installation - the combination of a Type-17 point for quick starts and a 6-Lobe drive to prevent cam-out keeps the installation process efficient, reducing driver wear and installer frustration on large decking projects.
• Color variety for design flexibility - with painted heads available in 13 colors matched to most major decking brands, it is straightforward to find the right color match for a cohesive, finished deck appearance without visible fastener contrast.

Frequently Asked Questions

What type of decking is this screw designed for?

This trim-head screw is designed for use with PVC and composite decking installations. The color-matched Tan 04 painted head is available to blend with most major PVC and composite decking manufacturers, and the Type 305 stainless steel construction handles the corrosive conditions common in marine and high-exposure deck environments.

Why use a 6-Lobe drive instead of a standard Phillips or square drive?

The T15 6-Lobe drive reduces cam-out - the slipping that occurs when a driver bit loses contact with the fastener head under torque. This means easier, more controlled driving, less wear on your driver bit, and a cleaner finished result without stripped heads.

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

The Type-17 point is designed for fast starts and typically reduces or eliminates the need for pre-drilling during installation. However, pre-drilling is recommended near board ends to help prevent splitting, particularly with composite and PVC materials.

Is Type 305 stainless steel suitable for marine or waterfront deck applications?

Type 305 stainless steel provides superior corrosion resistance and is well-suited for marine and high-exposure environments. For seaside applications where even greater corrosion resistance may be needed, Type 316 stainless steel versions are also available from Simpson.
