Simpson #7 x 2-1/4" Black Trim-Head Screw with T15 6-Lobe Drive in Type 305 Stainless Steel is engineered for clean, professional deck installations on PVC and composite decking surfaces. The low-profile trim-style head sits nearly flush against the decking material, making fasteners far less noticeable than standard screw heads - delivering a refined, finished appearance on outdoor decks. With a black painted finish over Type 305 stainless steel construction, these screws combine corrosion resistance with color-matched aesthetics, making them a practical choice for high-exposure outdoor environments including marine and coastal applications.

Key Features

• Trim Head design with 0.230" head diameter - sits low and inconspicuously on the decking surface for a clean, polished finish that lets the decking material take center stage
• Type 305 Stainless Steel material - provides superior corrosion resistance in marine, coastal, and high-exposure outdoor environments where standard fasteners may fail prematurely
• Black painted finish - color-matched to blend seamlessly with most major PVC and composite decking manufacturers, reducing the visual contrast between fastener and deck surface
• T15 6-Lobe drive system - helps prevent driver-bit cam-out during installation, resulting in easier, more controlled driving and extended bit life over the course of a project
• Type-17 point - self-drilling tip enables fast, clean starts without pre-drilling in most applications, speeding up installation and reducing labor
• Coarse thread pattern - draws decking boards and other material tightly to the framing for a secure, stable connection that resists movement and squeaking over time
• 2-1/4" length at #7 screw size - sized appropriately for PVC and composite deck board fastening, providing sufficient thread engagement into the framing below

Why This Product

• Designed specifically for PVC and composite decking - the trim-head profile and black painted finish are purpose-built for the aesthetic demands of synthetic decking materials, where visible fasteners detract from the finished look
• Type 305 stainless steel for long-term durability - ideal for marine environments, waterfront properties, or any high-exposure installation where moisture and humidity put ordinary steel fasteners at risk of rust and staining
• Available in 13 painted head colors - engineered to blend with most major PVC and composite decking brands, giving installers and homeowners flexibility to match nearly any deck color without compromise
• 6-Lobe drive reduces installation frustration - the T15 6-lobe recess provides a positive bit engagement that minimizes cam-out, protecting both the screw head finish and the surrounding deck surface during fastening

Frequently Asked Questions

What types of decking are these screws designed for?

These trim-head screws are designed for use with PVC and composite decking installations. The low-profile trim head and color-matched black painted finish are specifically engineered to blend with most major PVC and composite decking manufacturers, providing a clean and inconspicuous appearance on the finished deck surface.

Why choose Type 305 Stainless Steel for a deck fastener?

Type 305 Stainless Steel provides superior corrosion resistance, making these screws well-suited for marine environments, waterfront decks, and other high-exposure outdoor installations where moisture, humidity, and salt air can cause standard fasteners to corrode and stain the surrounding decking material.

What is a Type-17 point and why does it matter for installation?

The Type-17 point is a self-drilling screw tip that enables fast, clean starts when driving into decking and framing material. It reduces the need for pre-drilling in most applications - though pre-drilling is recommended near board ends to prevent splitting - which speeds up the installation process and helps maintain a tidy work surface.

What drive bit is required for these screws?

These screws use a T15 6-Lobe drive, which requires a T15 6-lobe (Torx-style) driver bit. The 6-lobe recess provides a secure, positive engagement with the bit, helping to prevent cam-out during driving and extending the usable life of the driver bit across large-scale deck installations.
