Engineered to power through wood and embed cleanly into steel substrates, the Simpson Strong‑Tie Strong‑Drive TFG1475R1000 TF Screws are a go-to solution for structural and heavy-duty framing applications. Whether you're fastening wood joists, studs, or furring strips to steel framing, these fasteners eliminate the need for predrilling-saving time and increasing productivity on the job.

Multiple diameter, length, and finish options are available to meet the demands of your specific project and environment. All variants offer the same high-performance design, combining aggressive holding power with corrosion resistance and a clean, flush finish.

Key Features

• #5 Self-Drilling Point with Wings: Eliminates predrilling by boring through wood and steel (up to 15⁄32" thick) in one pass.
• Flat Head with Nibs: Sits flush and resists pull-through in wood while providing a clean finish.
• 6‑Lobe (T-Star) Drive: Offers improved bit engagement and reduces cam-out—ideal for repetitive driving or auto-feed systems.
• Available Finishes: Choose between mechanically galvanized (N2000®) for corrosion protection or black phosphate for dry, interior applications.
• Code-Listed & Load-Rated: Tested and approved for structural use in wood-to-steel applications.
• Collated Options: Compatible with auto-feed systems to boost efficiency on large-scale installations.

Applications

TF screws are purpose-built for fastening wood directly into steel framing members in both new builds and retrofits. Ideal for:

• Wood joists, studs, or blocking to steel tracks or framing
• Furring strips or sheathing panels to metal substrates
• General commercial framing or residential retrofit jobs

Whether you’re working in the field or shop, these screws deliver holding strength and code compliance across diverse jobsite conditions.

Installation Tips

1. Match your screw size to materials: Select a length that allows proper embedment in the steel substrate after penetrating the wood member.
2. Use a T-star driver bit: The 6-lobe recess provides superior control and minimizes stripping.
3. Drive with confidence: No predrilling required for most applications. The screw will cut cleanly through both wood and steel.
4. Ensure flush seating: Nibs under the flat head help it set cleanly into the wood for a professional finish.
5. Finish for the environment: Use N2000® galvanized screws for outdoor or exposed steel and black phosphate for interior use.

Looking for a screw that bridges wood and steel with ease? The TF Screw is a structural performer ready for your toughest framing jobs.
