T/CSTM 00390.3-2020 Corrosion-resistant steel for bridges - Part 3: Steel for bolted joint pairs for large hexagonal head bolts
Basic Information
Scope
Scope: This part specifies the terms and definitions of steel for large hexagonal head bolt connections used in weather-resistant bridges, including large hexagonal head bolts, large hexagonal nuts, round steel for washers, wire rod, and steel strips. It also covers the designation methods of steel grades, order content, dimensions, shapes, weights, and allowable deviations, technical requirements, test methods, inspection rules, and packaging, marking, and quality certificates. This part applies to high-strength bolts and nuts used in steel structures of railway and highway bridges in rural and industrial atmospheric environments made of weather-resistant steel. It does not apply to high-strength bolts and nuts used in marine atmospheric environments.
