The Simpson Strong-Drive TB Wood-to-Steel Collated Screw, #14 x 1-9/16 in., Yellow Zinc, 1,000-Qty is a structural fastener from Simpson engineered to securely fasten wood to hot-rolled steel in high-volume applications. Designed specifically for use with the Simpson Strong-Tie Quik Drive auto-feed screw driving system, this collated screw streamlines installation on demanding jobs such as wood truck beds and trailer flooring - delivering consistent, repeatable results with every drive. A #4 drill point with wings, tapping threads, and a T30 6-lobe drive work together to make penetration fast and cam-out far less likely, even during extended runs.

Key Features

• Straight collation compatible with the Quik Drive PROHSD60 auto-feed system - feeds screws automatically so crews drive faster with less fatigue on large-scale wood-to-steel projects
• Flat head with nibs - nibs bite into the wood surface and pull the head flush cleanly, eliminating the need for a separate countersinking step
• T30 6-lobe drive - reduces driver-bit cam-outs during installation, meaning fewer stripped heads, less wasted time, and a more efficient workflow
• #4 drill point with wings - the self-drilling tip bores through wood and into steel without a pilot hole, while wings clear the wood plug for a cleaner, faster bite into the steel
• Tapping threads - cut directly into hot-rolled steel to form a secure mechanical connection between the wood and steel substrate
• Yellow zinc coating applied in accordance with ASTM F1941 - meets a recognized standard for coating application, giving buyers confidence in finish consistency across the full quantity
• Driver bit included - the correct T30 bit ships with every box, so the crew can start driving immediately without sourcing additional tooling

Why This Product

• Built for auto-feed speed on structural wood-to-steel work - straight collation and Quik Drive system compatibility let installers drive screws rapidly and consistently across nailers, ledgers, truck beds, and trailer flooring without stopping to hand-load each fastener
• Self-drilling, no-pilot-hole design saves meaningful time - the #4 drill point with wings penetrates wood and bites into hot-rolled steel in one motion, cutting out the pre-drilling step that slows traditional fastening workflows
• Reduced cam-out means cleaner results and less rework - the T30 6-lobe drive keeps the bit engaged through the full drive cycle, protecting screw heads and wood surfaces from the damage that repeated cam-outs cause
• Ready to install right out of the box - with a driver bit already included, the TB collated screw ships as a complete fastening solution so no additional accessories are needed to get started

Frequently Asked Questions

What driving system is the TB1440S designed to work with?

The TB1440S is designed to work with the Simpson Strong-Tie Quik Drive PROHSD60 auto-feed screw driving system or attachment, which uses the screw's straight collation for rapid, consistent installation.

What drive type does the TB1440S use, and why does it matter?

The TB1440S features a T30 6-lobe drive. This drive style reduces driver-bit cam-outs during installation, resulting in easier and more efficient fastening - especially beneficial in high-volume applications.

What coating is applied to the TB1440S, and does it meet any standards?

The TB1440S is coated with a yellow zinc finish applied in accordance with ASTM F1941, providing a standardized level of corrosion resistance for the coating.

Can the TB1440S be used for hand-drive fastening as well as auto-feed driving?

Yes. While the TB1440S collated screw is optimized for use with the Simpson Strong-Tie Quik Drive auto-feed system, the TB Wood-to-Steel screw is also available in bulk format for hand-drive fastening applications.
