Application Summary AI generated
This standard specifies the dimensions, technical requirements, and marking for large-width-across-flats hexagon bolts in property classes 8.8 and 10.9, with thread lengths conforming to GB/T 3106. It is applied in steel structure connections, such as bridges, buildings, and heavy machinery, where high-strength bolting is required for load-bearing joints. The product grade C designation indicates it is intended for general engineering applications with less stringent tolerance requirements.
