ABSTRACT:
Fasteners composed of a composite material constituted by a ceramic matrix reinforced with refractory fibers for use in the assembling and dissembling of structures likely to be subjected to high temperatures. The fasteners, which can comprise screws, nuts and bolts, can include a threaded rod, possibly comprising a head, and at least one nut cooperating with the rod. The threads of the rod and the nut are round threads. Further, the male and female portions of the threads have the same theoretical profile to within machining tolerance and functional clearance.
