To provide a grooved nut capable of suspending and supporting an object to be lifted easily and safely while preventing damage of the object to be lifted and a wire even when the object to be lifted has an extremely large weight.SOLUTION: A grooved nut is a nut 1 screwed to a bolt part included in an object to be lifted which is suspended and supported by a wire. The grooved nut has a flange part 3 provided with a groove part 2 in an outer periphery so as to prevent positional deviation of the wire in a thickness direction when the wire is wound around it. The grooved nut is screwed to the bolt part and the wire is wound around the groove part 2 of the flange part 3 so as to make it possible to suspend and support the object to be lifted with the wire.SELECTED DRAWING: Figure 1
