Wood such as SillBor®, treated with the DOT type of borate, has been found to be no more corrosive than traditional CCA-treated wood. Code-compliant hardware is adequate.
While galvanized fasteners and connectors are preferable, the use of non-galvanized hardware of sizes and types approved by the model code is acceptable when attaching joists, studs, or other framing to SillBor® wood, provided the wood will remain dry in service, protected from weather and water. Under similar conditions, the use of standard galvanized strapping or mild steel anchor bolts ½" in diameter and larger is also acceptable for fastening SillBor® wood to foundations.
