Product Description
The Simpson Strong-Drive TF Wood-to-Steel Screw is a #14 x 3 in. load-rated structural fastener engineered and extensively tested for demanding wood-to-metal applications. Built to bore through wood and penetrate steel up to 15/32 in. thick, this collated screw delivers a clean, flush install without any predrilling - making it a reliable choice for structural framing, truck beds, and trailer flooring alike. Each 750-count package features straight collation for use with the Simpson Quik Drive auto-feed screw driving system, and a T30 6-lobe driver bit is included.
Key Features
- T30 6-lobe recessed drive with included driver bit - provides a secure engagement that reduces cam-out, extends bit life, and keeps your work moving without hunting for a separate bit
- #5 drill point with wings - bores cleanly through the wood member before engaging the steel, eliminating wood fiber interference and reducing driving torque
- Flat head with nibs - countersinks flush into the wood surface with minimal effort and delivers excellent pull-through resistance for a structurally sound connection
- Self-tapping tapping threads at 14 TPI - cut directly into the steel member without a pilot hole, locking the fastener securely in place and saving significant installation time
- No predrilling required - the screw handles wood and steel penetration in a single step, streamlining workflow on structural wood-to-metal connections
- N2000 Mechanically Galvanized coating - provides a medium level of corrosion resistance suited for applications where exposure to moisture or the elements is a consideration
- Straight collation compatible with Quik Drive auto-feed systems - works with the Simpson Strong-Tie Quik Drive PROHSD75 and PROHSD75M attachments for high-volume, consistent fastening
Why This Product
- One screw does it all - the combination of a #5 drill point with wings and self-tapping threads means a single fastener handles wood boring and steel threading in one pass, eliminating the need for predrilling or pilot holes and reducing labor on large jobs
- Built for auto-feed production driving - straight collation and full compatibility with the Simpson Quik Drive system allow crews to drive hundreds of fasteners quickly and consistently, making this screw especially well-suited for repetitive structural applications like trailer flooring and wood-to-steel framing
- Engineered for structural confidence - load-rated and extensively tested by Simpson for wood-to-metal connections, this fastener is designed to perform where structural integrity matters, not just general-purpose fastening
- Flush, pull-through-resistant finish every time - the flat head with nibs countersinks automatically as the screw seats, leaving a clean surface without overdriving while maximizing holding power against pull-through forces

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.
