The Simpson Strong-Drive TB Wood-to-Steel Screw #12 x 2-3/8 in. Black Phosphate Collated T30 1000-Pack is a structural fastener from Simpson engineered specifically for joining wood to hot-rolled steel in demanding applications such as nailers, ledgers, and wood truck bed installations. Designed for use with the Simpson Strong-Tie Quik Drive auto-feed screw driving system, this straight-collated screw combines a self-drilling point, tapping threads, and a T30 6-lobe drive to deliver fast, consistent, high-volume fastening with minimal effort. The black phosphate coating makes it well-suited for dry, low corrosion interior environments where structural performance and installation speed are the priority.

Key Features

• Straight collation - ensures seamless, uninterrupted compatibility with Quik Drive auto-feed screw driving systems for efficient high-volume installation
• Flat head with nibs - allows the screw to countersink cleanly into wood without pre-drilling a recess, saving time and producing a flush finish
• T30 6-lobe drive - reduces driver-bit cam-outs during fastening, resulting in easier installation, less wasted effort, and reduced wear on driver bits
• Driver bit included - the correct T30 driver bit is provided in the box, so installation can begin immediately without sourcing a separate accessory
• #4 drill point with wings - self-drills through wood and into hot-rolled steel cleanly, eliminating the need for pre-drilling pilot holes and accelerating the fastening process
• Tapping threads - cut into the steel substrate to form a secure, tight mechanical connection between wood and steel members
• Black phosphate coating - intended for dry, low corrosion applications, providing a functional protective finish in interior structural settings
• 1,000-count packaging - provides a high-volume supply suited to production-scale jobs such as truck bed flooring, trailer decking, and framing work

Why This Product

• Built for Quik Drive auto-feed systems - the straight collation and screw geometry are matched to the Simpson Strong-Tie Quik Drive PROHSD60 and PROHSD60M, so installers get reliable feeding and consistent depth control throughout the job without manual adjustments between fasteners
• Eliminates pre-drilling on wood-to-steel connections - the #4 drill point with wings bores through wood and self-taps into hot-rolled steel in a single pass, cutting labor time significantly on applications like truck bed installations and structural ledger attachments
• Reduces installation errors and fatigue - the T30 6-lobe drive actively resists cam-outs, meaning fewer stripped fasteners, less rework, and reduced strain on the installer during extended high-volume screw driving
• Purpose-matched for wood-to-steel structural work - tapping threads, a hardened drill point, and a flat countersinking head work together as a system optimized for the specific mechanical demands of fastening wood framing members and decking to steel substrates

Frequently Asked Questions

What auto-feed screw driving systems are compatible with the TBP1260S?

The TBP1260S installs with the Simpson Strong-Tie Quik Drive PROHSD60 or PROHSD60M auto-feed screw driving systems. Its straight collation is specifically designed for seamless use with these tools.

Is the black phosphate coating suitable for outdoor or high-moisture environments?

No. The black phosphate coating on the TBP1260S is intended for dry, low corrosion applications only. It is not recommended for exterior, high-humidity, or chemically exposed environments.

What is the benefit of the T30 6-lobe drive on this screw?

The T30 6-lobe drive is engineered to reduce driver-bit cam-outs during installation, which results in easier, more efficient fastening and less wear on the driver bit - especially important during high-volume collated screw driving.

Can the TBP1260S be used for hand-drive fastening instead of with an auto-feed system?

Yes. While the TBP1260S is designed to work with the Simpson Strong-Tie Quik Drive auto-feed screw driving system, the TB Wood-to-Steel screw is also available in bulk for hand-drive fastening applications.
