Simpson #7 x 2-1/4" Trim-Head Decking Screw in Gray 03 with T15 6-Lobe Drive and Type 305 Stainless Steel brings together corrosion-resistant construction and a low-profile head design for clean, professional installations on PVC and composite deck surfaces. Engineered by Simpson for marine and high-exposure outdoor environments, these stainless steel trim-head screws fasten decking boards securely while the painted Gray 03 head blends seamlessly with the deck surface for a finished, polished appearance.

Key Features

• Trim-head design with 0.230" head diameter - sits flush and low-profile on the decking surface, reducing the visual footprint of each fastener for a cleaner finished look on PVC and composite boards.
• Type 305 Stainless Steel material and finish - delivers superior corrosion resistance in marine environments, high-moisture zones, and other high-exposure outdoor settings where standard fasteners would degrade.
• Gray 03 painted head color - matched to blend with most major PVC and composite decking manufacturers, creating a cohesive, color-coordinated deck surface without visible hardware contrast.
• T15 6-Lobe drive type - reduces driver-bit cam-out during installation, resulting in easier, more controlled driving and extended bit life on long decking projects.
• Type-17 point - self-starting tip bites into decking material quickly for faster starts without pre-drilling into the field, speeding up installation on PVC and composite surfaces.
• Coarse threads - draw decking boards and substrate material tightly together, creating a firm, stable connection between the decking surface and the underlying framing.
• #7 screw size at 2-1/4" length - sized appropriately for common PVC and composite decking board thicknesses, providing adequate thread engagement into the framing below.
• Approximately 138 screws per pound - a consistent count-per-weight benchmark that helps estimate quantities needed when planning decking projects by material weight.

Why This Product

• Purpose-built for PVC and composite decking in demanding environments - the combination of Type 305 Stainless Steel and a painted trim head addresses the dual needs of corrosion resistance and visual compatibility that composite and PVC deck installations require in marine or weathered settings.
• The trim-head format solves the problem of visible fasteners - standard screw heads stand out against smooth composite surfaces; the special trim-head geometry minimizes the hardware footprint so the deck surface remains the visual focus.
• Color-matched painted heads in 13 available colors - rather than using a generic fastener that contrasts with the decking, these screws are available in colors designed to match most major PVC and composite decking product lines, giving installers a finished result without additional touch-up steps.
• 6-Lobe T15 drive reduces installation fatigue on large deck projects - the anti-cam-out drive system keeps the bit engaged through the full drive cycle, which matters when driving hundreds of screws into composite material over the course of a full deck installation.

Frequently Asked Questions

What type of decking material is this screw designed for?

These trim-head screws are designed for use with PVC and composite decking. The trim-head profile, Type-17 self-starting point, and coarse thread pattern are all suited to the characteristics of engineered decking boards, and the painted Gray 03 head is color-matched to blend with most major PVC and composite decking manufacturers.

Is Type 305 Stainless Steel suitable for marine or coastal deck installations?

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 is needed, Type 316 Stainless Steel is also available in the Simpson trim-head line.

Does the Type-17 point require pre-drilling before installation?

The Type-17 point is designed for fast starts and does not require pre-drilling in the field. However, pre-drilling is recommended near board ends to help prevent splitting of the decking material.

What driver bit does this screw require?

This screw uses a T15 6-Lobe drive, which requires a matching T15 6-Lobe driver bit. The 6-Lobe design reduces cam-out during driving, which helps extend bit life and provides more consistent driving results compared to conventional drive types.
