A shaft of a door handle to be installed in a door includes a limited length threaded segment for engaging a commensurately threaded rose to effect penetration and subsequent threaded disengagement therebetween. The threaded disengagement permits relative rotation without axial displacement and axial withdrawal of the shaft is prevented due to interference between the threaded segments. Upon positional locking of the rose with the door and mating of the door handle with a door bolt, the resulting limited relative rotation between the door handle and the rose in combination with the axial displacement limited by the interfering thread segments prevent threaded disengagement and removal of the door handle.
