Product Description
The Simpson Strong-Tie Strong-Drive TF Wood-to-Steel Screw (Model TFG1475S) is a #14 x 3-in. load-rated structural fastener engineered and extensively tested to meet the needs of the most demanding wood-to-metal applications. Designed to bore through wood and into steel up to 15/32-in. thick, this collated screw combines a flat head with nibs for flush, pull-through-resistant countersinking, a #5 drill point with wings that clears wood fiber before engaging the steel member, and self-tapping threads that lock securely into the steel - all with no predrilling required. Finished in N2000 Mechanically Galvanized coating for medium-level corrosion resistance, these screws feature straight collation that is fully compatible with the Simpson Strong-Tie Quik Drive auto-feed screw driving system. Each package contains 750 fasteners along with a T30 6-lobe driver bit.

Frequently Asked Questions
- What auto-feed screw driving system is this screw compatible with?
- These screws feature straight collation that is compatible with the Simpson Strong-Tie Quik Drive auto-feed screw driving system, specifically the PROHSD75 and PROHSD75M attachments. A T30 6-lobe driver bit is included with each 750-count package, and a replacement bit is available under model BITTX30.
- Does this screw require predrilling before installation?
- No predrilling is required. The #5 drill point with wings bores through the wood member first, then engages and drills into the steel member on its own. The self-tapping threads then lock the fastener securely into the steel without the need for a pilot hole.
- How thick of a steel member can this screw penetrate?
- The Simpson Strong-Drive TF Wood-to-Steel screw is designed to bore through wood and into steel up to 15/32-in. thick, making it suitable for demanding structural wood-to-metal applications.
- What level of corrosion resistance does the N2000 Mechanically Galvanized coating provide?
- The N2000 Mechanically Galvanized coating provides a medium level of corrosion resistance. This finish is applied to the #14 x 3-in. screw to help protect it in structural applications where moderate corrosion resistance is required.
