    摘要: There is provided a nut having a thread portion having a female thread, a metallic plate portion having a base segment, and a hardness gradient portion provided between the thread portion and the metallic plate portion. The thread portion, metallic plate portion and the hardness gradient portion are monolithic each other, a metallographic structure of the metallic plate portion differs from a metallographic structure of the thread portion and a hardness of the hardness gradient portion is lower than a hardness of the thread portion and lowers from the thread portion toward the metallic plate portion.
