The invention discloses a gasket for inspecting a bolt ball joint and further discloses a using method of the gasket for inspecting the bolt ball joint. The gasket is characterized in that the gasketis made of a paper material; a receding hole which can allow a threaded rod in the bolt ball joint to penetrate through is formed in the gasket in a penetrating mode in the thickness direction of thegasket; a part exceeding the range of the end face of the front end of a sleeve in the bolt ball joint is arranged outside the gasket to form a pulling part; an easy-to-tear line is further arranged on the gasket, and the extending line of the easy-to-tear line is located outside the pulling part area on the gasket; the structure strength at the easy-to-tear line is smaller than that of other positions of the gasket; and the inner end of the easy-to-tear line is connected with the contour line of the receding hole, and the distance between the outer end of the easy-to-tear line and the outer contour line of the gasket is smaller than the distance between any point of the contour line of the receding hole and the outer contour line of the gasket. The gasket for inspecting the bolt ball joint and the using method thereof have the advantages that the structure is simple, the bolt ball joint can be completely inspected conveniently, the inspection efficiency can be improved, and the inspection labor intensity can be reduced.
