The present disclosure relates to the field of liquid crystal displays (LCDs), and more particularly to a sheet metal part for an LCD device, an LCD device, and a method for manufacturing a sheet metal part for an LCD device. The sheet metal part comprises an inner hole flange, the flange comprises an internal thread, and a circumference of a cross section of the inner hole comprises at least one protrusion protruding to a direction of a center of circle of cross section of the inner hole. The sheet metal part for the LCD device of the present disclosure comprises the inner hole flange. The flange comprises the internal thread, and the circumference of the cross section of the inner hole comprises at least one protrusion protruding to the direction of the center of circle of cross section of the inner hole. The protrusion changes a shape of the inner hole, so that the inner hole is not a complete circular hole any more. After tapping the standard internal thread on the flange, the thread tooth of the protrusion is deep, thereby bearing much torsion; the thread teeth of other parts are shallow, the thread wall is thick; thus, the strength of the inner hole is increased, thereby improving the locking reliability of the thread of the inner hole on the whole. |
