Summary:The utility model discloses a special gauge for detecting the aperture of a round hole of a fence column, which relates to the field of special gauges for the aperture of metal products and comprises a gauge main body, a go end and a not-go end, the go end and the not-go end are arranged at two ends of the gauge main body, the special gauge is integrally a cylinder, and the diameters of the go end and the not-go end are smaller than those of the gauge main body. An annular not-go-end mark is arranged at the position close to the not-go-end; the diameter of the not-go end is slightly greater than that of the go end; the diameter of the go end and the diameter of the no-go end are the upper limit and the lower limit of the allowable tolerance of the circular hole diameter respectively. The special gauge is simple in structure and easy to operate, and can be easily mastered without professionals. After the special gauge is used, the bore diameter machining tolerance of the fence stand column can be ensured to be
