A shim nut and screw bolt assembly for rigidly securing together a pair of spaced apart components, the shim nut of this assembly having internal threads and opposite hand external threads which threadedly engage a nut fixed to or forming part of the first component, a screw bolt of this assembly extending through an aperture in the second component and having its threaded shank in threaded engagement with the internal thread of the shim nut whereby rotation of the screw bolt in a fastener direction will first cause the screw bolt to extend into the shim nut a sufficient axial distance whereby friction between this screw bolt and the shim nut then becomes such that the shim nut will be rotated to move it a sufficient axial distance outward relative to the first component into abutment with the second component after which, further rotation of the screw bolt in the fastening direction, will effect securement of the second component to the shim nut by the screw bolt and thereby attachment of the second component to the first component in spaced apart relation thereto.
