The Building Code
Using bolts in buildings and structures is covered by Clause B1 Structure, Clause B2 Durability and Clause F2 Hazardous Building Materials. The manufacture and supply of high-strength steel bolts with associated nuts and washers for structural engineering are specified by the Australian/New Zealand joint Standard AS/NZS 1252. Building Code Verification Method B1/VM1 references NZS 3404 Steel Structures Standard, which in turn references AS/NZS 1252.
