Abstract

PURPOSE: To improve anticorrosive character either by surface treatment of a bolt or a female screw thread or by using soft materials for the female thread of a nut in order to make the surface of male thread portion of the bolt harder than that of female thread portion of the nut.
CONSTITUTION: A surface of a male screw thread portion of a bolt is hardened by surface treatment in order to make a hardness of that portion relatively harder than a female portion of a nut, or a nut is made of softer materials, thereby, scratches generated upon fitting may only be caused on the surface of the female screw thread portion of the nut. Damages on the exposed surface of the bolt may be eliminated and the female thread portion for the nut is contacting closely with the male thread for the bolt always perfectly at any position of the nut, consequently, the bolt and nub after fitting may be rendered to be anticorrosive perfectly because they are protected from corrosive circumstances.
