Simpson Strong-Tie H series of hurricane ties provide a positive connection between truss/rafter and the wall of the structure to resist wind and seismic forces. The Strong-Tie H2AZ Hurricane Tie features a Zmax finish for added corrosion resistance and requires the use of hot-dip galvanized fasteners which meet the specifications of ASTM A153.
