SDWF Floor-to-Floor Screw

From: Simpson Strong-Tie

Simpson Strong-Tie’s SDWF Floor-to-Floor screw attaches upper and lower walls together from the top, spanning a floor system to create a strong connection between floors. The screw is designed to simplify the wind uplift restraint connection while delivering performance over a structure’s lifetime as well as during an extreme weather event. It can be installed from inside a structure before or after exterior sheathing is applied.
