The Simpson Strong-Drive TB Wood-to-Steel Screw, #12 x 2-3/8 in., N2000 Mechanically Galvanized is a structural fastener engineered by Simpson Strong-Tie for reliable wood-to-metal connections in demanding construction and framing applications. Built to fasten wood to steel with a maximum recommended steel thickness of up to 1/4 in., this screw combines a self-drilling point, tapping threads, and a corrosion-resistant coating into a single solution purpose-built for interior and noncorrosive environments. Whether you are working on light steel framing, metal stud applications, or structural wood-to-steel assemblies, this fastener is designed to deliver consistent, high-strength performance installation after installation.

Key Features

• Flat head with nibs - allows the screw to countersink effortlessly into wood, producing a clean, flush finish without additional prep work.
• T30 6-lobe drive - reduces driver-bit cam-outs during installation, giving you more control, less bit wear, and faster, more efficient driving.
• #4 drill point with wings - self-drills through steel and helps clear material as it penetrates, reducing the resistance encountered when driving into metal.
• Tapping threads - cut their own mating threads as the screw is driven, eliminating the need for pre-tapping and speeding up the fastening process.
• N2000 Mechanically Galvanized coating - provides a medium level of corrosion resistance, making these screws well suited for dry, interior, or noncorrosive job-site conditions.
• Rated for steel up to 1/4 in. thick - gives you a clear, engineer-backed working parameter so you can specify and install with confidence.

Why This Product

• Engineered specifically for wood-to-steel fastening - unlike general-purpose fasteners, every design detail of this screw - the drill point, wing tip, tapping threads, and flat nibed head - works together to handle the specific demands of attaching wood members to steel substrates.
• Cam-out resistance built into the drive system - the T30 6-lobe drive is not just a head style; it actively reduces the slippage that slows down installation and damages screw heads, keeping your workflow moving and your driver bits lasting longer.
• No pre-drilling or pre-tapping required - the #4 drill point with wings and self-tapping thread design let the screw do the prep work itself, reducing labor steps and keeping installation straightforward on the job site.
• Backed by Simpson Strong-Tie engineering - this screw comes from a manufacturer with a well-established focus on structural fastening solutions, and is supplied in a bulk quantity that includes a driver bit, making it a practical choice for contractors and builders tackling larger wood-to-steel framing projects.

Frequently Asked Questions

What is the maximum steel thickness these screws are rated for?

The Simpson Strong-Drive TB Wood-to-Steel Screw TBG1260R1500 is designed for use with steel up to a maximum recommended thickness of 1/4 in.

What type of drive does this screw use, and why does it matter?

This screw uses a T30 6-lobe drive, which is engineered to reduce driver-bit cam-outs during installation. This results in easier, more controlled driving and less wear on both the screw head and the driver bit.

Is this screw suitable for outdoor or corrosive environments?

No. The TBG1260R1500 is designed for use in dry, interior or noncorrosive environments only. While the N2000 Mechanically Galvanized coating provides a medium level of corrosion resistance, it is not intended for exterior, wet, or corrosive applications.

What drill point and thread type does this screw feature?

This screw features a #4 drill point with wings for self-drilling performance into steel, along with tapping threads that help create a secure mechanical connection between the wood and steel substrate.
