In the late 1930s, bolt connection was gradually replaced by rivet connection, which was only used as a temporary fixing measure in component assembly. High strength bolt connection method appeared in the 1950s. High strength bolts are made of medium carbon steel or medium carbon alloy steel, and their strength is 2 ~ 3 times higher than that of ordinary bolts.
