The Strong-Drive TB is built for one job: fastening wood to steel without babysitting the connection. The self-drilling, wing-tip point bores through hot-rolled steel up to 1/4" thick and breaks off clean on contact, so there's no pre-drilling, no split lumber, and no guessing whether the screw will bite. The flat head with under-head nibs countersinks cleanly into wood nailers, sleepers, and subflooring, and the collated strip format runs straight through Simpson's Quik Drive auto-feed system for fast, consistent installs on job-lot runs. Available in a range of diameters, lengths, coatings, and drive styles (square or 6-lobe, depending on the option selected), the TB screw is a go-to for crews fastening wood assemblies to structural steel on commercial, modular, and trailer/truck bed work.

Key Features

• Self-drilling point with wings bores through steel and clears the hole without splitting the wood, eliminating a separate pre-drilling step.
• Flat head with under-head nibs seats flush or slightly recessed for a clean, consistent countersink every time.
• Drive recess (square or 6-lobe, depending on the option selected) resists cam-out for steadier driving under load.
• Straight collation runs through Simpson Quik Drive auto-feed systems for high-volume, repeatable installs, with hand-drive use also supported.
• Coating options available for different corrosion-exposure needs; match the coating to the job's environment rather than assuming interchangeability.

Applications

• Fastening wood nailers, sleepers, subflooring, and other wood assemblies to steel framing or hot-rolled steel members.
• Truck bed and trailer flooring installation.
• Commercial and modular construction where wood-to-steel connections are part of the assembly.
• Interior, non-corrosive environments; confirm coating and exposure rating before use in exterior or corrosive conditions.

Installation

• No pre-drilling required for steel up to 1/4" thick; the drill point does the work.
• Drive until the flat head sits flush or slightly recessed into the wood surface.
• Use with a compatible Quik Drive auto-feed attachment for collated strip installation, or drive by hand with the appropriate bit for the selected drive type.
• Always confirm steel gauge, coating, and application fit against the job spec and manufacturer documentation before ordering in bulk.
