The Simpson Strong-Drive TB Wood-to-Steel Screw (Collated) - #14 x 3 in., Black Phosphate (750-Qty) is a structural collated screw engineered by Simpson for securely fastening wood to hot-rolled steel. Built to work with the Simpson Strong-Tie Quik Drive auto-feed screw driving system, this screw is a go-to solution for high-volume installations such as wood truck beds and trailer flooring. The straight collation, #4 drill point with wings, and T30 6-lobe drive work together to deliver fast, consistent penetration with minimal effort - making it equally well-suited for nailers, ledgers, and other wood-to-steel framing applications.

Key Features

• Straight collation - compatible with the Simpson Strong-Tie Quik Drive PROHSD75 and PROHSD75M auto-feed systems, enabling high-speed, continuous driving without stopping to reload individual fasteners
• Flat head with nibs - the nibs assist with countersinking into wood surfaces for a clean, flush finish that requires no additional prep work
• T30 6-lobe drive - reduces driver-bit cam-outs during installation, resulting in easier driving, less bit wear, and a more consistent result across every fastener
• #4 drill point with wings - the self-drilling tip penetrates hot-rolled steel efficiently, eliminating the need for pre-drilling in appropriate conditions and keeping the work moving
• Tapping threads - thread into steel securely after the drill point clears, creating a strong mechanical connection between wood and steel members
• Black phosphate coating - intended for dry, low corrosion applications, providing a consistent finish across the full quantity of screws in the pack
• Driver bit included - the correct T30 bit ships with the screws so installation can begin immediately without sourcing additional tooling

Why This Product

• Purpose-built for wood-to-steel structural connections - unlike general-purpose fasteners, this screw is specifically designed for fastening wood to hot-rolled steel, making it a reliable choice for truck bed decking, trailer flooring, nailers, and ledger applications where connection integrity matters
• Auto-feed system compatibility cuts installation time significantly - straight collation engineered for the Quik Drive PROHSD75 and PROHSD75M means fewer interruptions, less fatigue, and faster project completion on high-count installations
• Cam-out-resistant T30 6-lobe drive protects both the fastener and the installer - reduced slippage means less stripped heads, less rework, and a cleaner finish across every screw driven into the assembly
• Everything needed to start driving is included - with a driver bit packed in alongside the screws, this is a ready-to-use solution for contractors and builders who need to get to work without additional preparation

Frequently Asked Questions

What auto-feed screw driving systems are compatible with the TBP1475S?

The TBP1475S installs with the Simpson Strong-Tie Quik Drive PROHSD75 and PROHSD75M auto-feed screw driving systems. Its straight collation is designed specifically to work seamlessly with these tools for fast, efficient installation.

What type of steel can the TB Wood-to-Steel screw be used with?

This screw is designed for fastening wood to hot-rolled steel. It features a #4 drill point with wings that enables it to penetrate steel efficiently without pre-drilling in appropriate conditions.

Is the TBP1475S suitable for outdoor or high-moisture environments?

The TBP1475S features a black phosphate coating, which is intended for dry, low corrosion applications. It is not recommended for environments with high moisture, direct weather exposure, or elevated corrosion risk.

Can the TB Wood-to-Steel screw be installed without the Quik Drive auto-feed system?

Yes. While the TBP1475S is designed for use with the Simpson Strong-Tie Quik Drive auto-feed system, the TB Wood-to-Steel screw is also available in bulk for hand-drive fastening. The T30 6-lobe drive reduces driver-bit cam-outs for easier installation by either method.
