Abstract: A one-way nut fastener includes a head portion having a first head portion provided with an opening and a second head portion and a handle portion connected to the head portion. When the head portion is rotated in a first direction, the head portion rotates along with a nut, which is installed on a pipe line and disposed in the opening, in the first direction. When the head portion is rotated in a second direction opposite to the first direction, the second head portion may be bent in the second direction at an angle from the first head portion.
