Zusammenfassung:	The tamper proof anchor bolt assembly includes a frangible nut assembly and a tamper resistant skirt attached to one end of an expandable anchor bolt device. An expandable anchoring means attached to the other end of the anchoring device expands to create a secure connection between the anchor bolt and a supporting structure in response to the application of torque to the frangible nut assembly. The frangible nut assembly includes a frangible connection which ruptures at a predetermined torque corresponding to the secure connection. The tamper resistant skirt is rotatably positioned around the entire periphery of the remaining frangible nut assembly to prevent a tool from upsetting the secure connection by applying a gripping force to the anchor bolt device.
