ABSTRACT:
The parts of a support structure which can be assembled together have rimmed holes and openings going through them centrally. A conical nut is screwed onto a countersunk screw which goes through the openings, and the nut has a conical surface which has a cone angle that is the same as the inner conical surface of the opening of a corresponding rimmed hole. The described screw connection is particularly well suited for support structures which are heavily stressed by shocks, vibrations or other disturbances and is found to be durably resistant under these conditions without additional means for securing the screw and nut.
