GB/T 5782 hexagonal head bolts are one of the commonly used hexagonal bolt models in Chinese national standards. They are mainly suitable for the assembly and fixation of some ordinary machinery and equipment. GB/T 5782 hexagonal head bolts have the appearance of a hexagonal cylinder with a hexagonal protrusion at the top, which can be tightened with a hexagonal wrench. This design allows the bolts to receive even force when tightened, improving the stability and reliability of the connection.
