<P>PROBLEM TO BE SOLVED: To provide a method and a device for inspecting a screw hole in which inspection of the screw hole can be performed while protecting threads of the screw hole by a simple method. <P>SOLUTION: In a method for inspecting a screw hole in which a screw hole 32 is inspected by using a thread gauge, when the thread gauge is moved in the direction of a center axis S by rotation of an adaptor 12 fitted into the thread gauge in a state where the thread gauge is screwed into the screw hole 32, a gap is provided between the adaptor 12 and the thread gauge in the direction of the center axis S while being formed by screwing a tip part 48 of the thread gauge into the screw hole 32 in a state where the movement distance in the direction of the center axis S per one rotation of the adaptor 12 is smaller than a pitch of the screw hole 32. <P>COPYRIGHT: (C)2013,JPO&INPIT |
