An assembly for a turbine engine includes at least a first part and a second part, and at least one bolt including a screw engaging with a nut. The screw extends through respective openings in the first part and in the second part. A bearing element of the bolt has an annular flange mounted between the screw or the nut and the first part. The flange has a bearing surface bearing that is tapered and forms an angle (α) with an additional bearing surface of the first part such that only an outer peripheral area of the flange bearing surface comes into contact with the additional bearing surface of the first part, in a non-tightened state of the bolt, the flange deformable such that when the nut is tightened on the screw, a larger area of the flange bearing surface bears on the additional bearing surface of the first part.
