FIELD: mechanics.
SUBSTANCE: invention relates to mechanical connections, which provide interconnections of the parts, made of a thermo-structural composite material. Bolt head rests on the recess formed in the first part by a conical countersinking. Nut head rests on the recess formed in the second part by a conical countersinking. During the fastening system axial expansion, the fastening system is configured to allow at least one of the two heads to tilt towards the recess produced by the conical countersinking in which it is located. Assembly comprises first and second parts made of a composite material held side by side by means of a fastening system comprising a bolt, having a flat head from which the threaded portion passes, and a nut having a flat head from which a shank passes, including a thread suitable for engaging with the bolt threaded portion.
EFFECT: technical result is enabling the connection reliability at thermal influences onto the connected parts.
