1. An assembly (1) for a turbine engine, said assembly (1) comprising:
at least a first part (2) and a second part (3), and
at least one bolt (4) including a screw (7) cooperating with a nut (8), said screw (7) extending throughout an orifice (11) of the first part (2) and an orifice (12) of the second part (3), the bolt (4) further including:
a bearing member comprising an annular flange (16) mounted between the screw (7) or the nut (8), on the one hand, and the first part (2), on the other hand, said flange (16) including a bearing surface (17) bearing, at least partially, on a complementary bearing surface (13) of the first part (2), characterized in that said bearing surface (17) of the flange (16) is frustoconical and forms an angle (a) with the complementary bearing surface (13) of the first part (2) so that only an outer peripheral area of said bearing surface (17) of the flange (16) comes into contact with the complementary bearing surface (13) of the first part (2), in an untightened state of the bolt (4), said flange (16) being deformable so that, when tightening said nut (8) on the screw (7), a larger area of the bearing surface (17) of the flange (16) bears on the complementary bearing surface (13) of the first part (2), said bearing member including a recessed annular groove extending at an inner periphery of the flange, the flange (16) being tapered in the direction of an outer periphery of the flange (16).
