ABSTRACT:
The present invention relates to a fastening member, a machine element set for fastening and a method of fastening the machine element for fastening so arranged that a through hole of a fastening member freely fastened to the shaft, the thread or the receiver portion of a thread member is formed into a narrow hole by warping, deforming, bending or twisting the fastening member so as to cause fastening edges to be fastened to the thread portion of the male thread member. When the male thread member is tightened, the narrow hole is restored to the original moderate through hole by the tightening force, so that the fastening member or members to be installed and held by the fastening member can be easily temporarily fixed. After the tightening work has been completed, the male thread member and the fastening member can be freely rotated with respect to each other, so that the damage of the corresponding element due to rubbing can be prevented.
