The Simpson Strong-Drive TB Wood-to-Steel Screw #14 x 2-3/8 in. Black Phosphate Collated T30 6-Lobe Flat Head is a structural collated fastener from Simpson engineered specifically for fastening wood to hot-rolled steel. Built to work with the Simpson Quik Drive auto-feed screw driving system, this screw is a go-to choice for wood truck beds, trailer flooring, nailers, ledgers, and other wood-to-steel connections where speed and holding strength matter. Its drill point with wings, tapping threads, and flat head with nibs combine to deliver clean, fast seating without pre-drilling, making it a practical solution for both production and job-site work in dry, low-corrosion environments.

Key Features

• Straight collation - compatible with the Simpson Quik Drive PROHSD60 and PROHSD60M auto-feed systems, keeping installation fast and continuous without stopping to reload
• Flat head with nibs for easy countersinking - the nibs cut into the wood surface as the screw seats, producing a flush finish without a separate countersink step
• T30 6-lobe drive - reduces driver-bit cam-outs during installation, meaning less bit wear, fewer fumbled fasteners, and more controlled driving at speed
• #4 drill point with wings - the drill point pierces hot-rolled steel cleanly while the wings ream the wood layer, eliminating the need for pre-drilling in most wood-to-steel applications
• Tapping threads - thread directly into steel without a tapped hole, saving time and setup steps on the job
• Black phosphate coating - intended for dry, low-corrosion applications, providing a surface finish suited to interior and protected environments
• Driver bit included - the correct T30 bit ships with the screws, so you can start work immediately without sourcing a separate accessory

Why This Product

• Purpose-built for wood-to-steel fastening - unlike general-purpose fasteners, the TB screw is specifically designed for structural connections between wood and hot-rolled steel, covering applications from truck bed decking to framing nailers and ledgers with a single, proven fastener
• Auto-feed system compatibility eliminates repetitive loading - straight collation matched to the Simpson Quik Drive PROHSD60 and PROHSD60M systems means significantly faster installation rates on high-volume jobs compared to hand-fed screws
• Drill point with wings means no pre-drilling - the #4 drill point self-pierces the steel substrate while wings clear the wood, cutting out an entire step in the fastening process and reducing labor time on the work surface
• Cam-out resistant drive design protects your work and your bits - the T30 6-lobe geometry keeps the bit seated during driving, reducing surface damage to the workpiece and extending the usable life of the included driver bit

Frequently Asked Questions

What auto-feed driving system is compatible with the TBP1460S?

The TBP1460S is designed to install with the Simpson Strong-Tie Quik Drive PROHSD60 or PROHSD60M auto-feed screw driving systems. Its straight collation is specifically suited for use with these tools.

What does the black phosphate coating mean for my application?

The black phosphate coating on the TBP1460S is intended for dry, low corrosion applications. It is not recommended for exterior, high-moisture, or high-corrosion 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 means less slippage, less wear on the bit, and faster, more controlled driving - especially beneficial when using an auto-feed system.

Can the TBP1460S be used without an auto-feed system?

The TB Wood-to-Steel screw is also available in bulk for hand-drive fastening; however, the TBP1460S specifically features straight collation designed for use with the Simpson Strong-Tie Quik Drive auto-feed screw driving system.
