Selecting the right fasteners will help ensure the longevity of your project. For the typical exterior structures exposed to the elements we advise builders to use hot-dipped galvanized fasteners (meeting ASTM A 153) and connectors (ASTM A 653 Class G185 sheet), or better, are recommended. For permanent wood foundations and corrosive environments, such as areas with saltwater spray, use 304 or 316 stainless steel. Always check with the fastener / connector/ flashing manufacturer’s recommendations prior to use.
