ABSTRACT:
A method for preventing loosening of a bolt fastened to a metallic member coated with an anticorrosive paint film without removing the paint film. Anticorrosive painting is applied on a metallic member, and then the painted film is thinned by applying an urging pressure onto a bolt seat surface portion of the painted metallic member by means of a press rod. The bolt seat surface portion of the metallic member also may be flattened by applying an urging pressure on the bolt seat surface portion by means of a press rod or by machining the bolt seat surface portion before the anticorrosive painting is applied on the metallic member, and then the painted film is thinned by applying an urging pressure onto the above-mentioned bolt seat surface portion by means of a press rod.
