The present invention relates to a pipe nut and a bolt. The pipe nut comprises: a pipe body which has a female screw part on one side to be screwed to a bolt member of an object; and a flange which is manufactured separately from the pipe body and then is inserted onto the outer surface of the pipe body to be fixed and coupled, and is fixed and coupled to the other object. Therefore, the present invention facilitates processing, increases strength by designing the flange to have a thick thickness, and prevents thermal deformation during a welding work. |
