Simpson Strong-Tie has extended its line of Strong-Drive TF Wood-to-Steel screws with options for increased corrosion resistance, particularly in trailer- floor applications.  

Table of Contents

Designed for performance and productivity in high-paced environments, the screws eliminate the need to predrill and install 26% faster than traditional predrill and hand-drive methods. The load-rated structural fasteners are engineered to bore through wood and into steel up to 15/32” thick. 

They feature a flat head with nibs for easy countersinking and pull-through resistance, along with a #5 drill point with wings to bore through the wood member before engaging with the steel. A six-lobe recess provides for secure driving, and self-tapping threads securely fasten into the steel member.
