The invention relates to a device for fixing two parts together, a first part having a fixing flange (2) comprising at least one through-orifice (3) for a threaded shank (4), carried by or integral with a second part (5), and means for making the nut (1) captive with respect to the flange (2) before it is screwed onto the threaded shank (4), characterized in that these means are of the type having a thread, the nut (1) having an externally threaded portion (11, 18) intended to be screwed into an internally tapped portion (8, 15) of the orifice (3) in the flange (2) or of an element (14) attached to the flange (2) and to pass completely through this internally tapped portion (8, 15) until it is housed in a cavity (9, 19) for axially retaining the nut (1), this allowing the nut (1) to rotate freely before it is screwed onto the threaded shank (4). The invention also relates to a turbomachine that utilizes this device and to an associated fixing method. |
