ABSTRACT:
A fastening or connecting device for fiber-reinforced ceramics to be used in high temperature ranges is in the form of a screw that is manufactured of a ceramic material in the shape of a plate having fiber layers with fibers oriented parallel to the surface of the plate. The plate thickness is less than 90% of the core diameter of the thread so that upon cutting a thread a discontinuous thread results. The bore of a complementary nut is provided with a continuous inner thread that cuts through the fiber layers at a right angle.
