ABSTRACT:
A drum lug includes a lug case and a lug nut. The lug case is fixed to an outer surface of a drum body. A threaded hole with which the lug bolt is threadably engaged is formed in the center of the lug nut. The lug nut is housed in the lug case with one end portion of the lug nut being exposed outside the lug case. A spot-faced hole communicating with the threaded hole is formed in the center of an outer end face of the lug nut in a predetermined depth. The hole diameter of the spot-faced hole is set to be slightly larger than the major diameter of the threaded hole.
