The material of the tested part is selected as the soft claw 5 according to the actual use requirement, and the principle that the large diameter, the medium diameter and the small diameter of the same type of threads (such as metric system, imperial system, uniform threads and the like) are only related to the nominal diameter and the thread pitch is utilized for calculation. Machining an M50 x 1 internal thread 5.2 (a thread minor diameter phi 49) at the center of the soft claw 5, and detecting by using a check thread plug gauge to meet the requirements of open and stop; and adjusting the hexagonal adjusting hole 1.1 to clamp the phi 27 standard core. At this point, the M28 x 1 thread ring gauge is completed, and the tool can be used to inspect workpieces with external threads of M28 x 1-6 h.
