The invention discloses a clamp for measuring the symmetry degree of axial and radial holes of a bolt, and relates to the technical field of measuring clamps. The measuring table is parallel to the positioning base; the positioning circular sleeve is rotatably arranged on the measuring table, and the measuring table is provided with angle marking lines around the circumferential direction of the positioning circular sleeve; the measuring core rod is eccentrically arranged on the positioning circular sleeve; the angle pointer is arranged on the surface of the positioning circular sleeve, and the angle pointer is located on a horizontal connecting line between the center of the positioning circular sleeve and the central axis of the measuring core rod. The method is used for measuring the hole symmetry degree of a part with the cylindrical radial hole characteristic, compared with a conventional measurement mode, the measurement error is small, the measurement preparation time is short, and the measurement effi
