The system has a group of studs (5) including threaded ends and presenting flaps (8) with non-circular contour, where the flaps are housed in a groove (10) provided in a support surface (2a) of one of parts e.g. turbine wheel`s flange. Each flap includes two plane surfaces (16, 17) that are opposite to each other and fixes the studs after slight rotation of the flaps connected between two studs. |
