Abstract: The structures of double wall carbon nanotubes (DWNTs) with atomic scale defects that can operate as bolt and nut pairs are analysed. The barriers and threshold forces for the relative motion of walls along the thread line and for twistoff are calculated for various types of defects. It is found that a type of defect does not influence the qualitative characteristics of a thread. The possibility of producing of the DWNT (which can operate as bolt and nut pair) by selforganisation is proposed.
