Abstract A fastening apparatus including a rachet-type tool adapted to transmit torque to a nut-type fastener. The tool includes a handle mounted to one or a plurality of tubular-type roller clutches which have the property of providing torque in only one direction. Openings in the handle are provided to enable a roller clutch to transmit unidirectional torque to the nut-type fastener and to allow the user to select the direction of this torque by selection of the appropriate opening. The particular configuration and material of the nut-type fastener is such that contact made by any device other than said tool for purposes of applying torque thereto would be reasonably detectable from subsequent examination of said fastener. A recessed portion of a fastened member is provided in which the nut-type fastener is attached to a complementary fastening member, said recessed portion being of special configuration adapted to receive the said tool for purposes of engaging the nut-type fastener while preventing access of commonly available tools.
In an enclosure formed by a base, side walls and a cover, the improvement which comprises: a recessed portion in said cover, said recessed portion having an aperture; a threaded member having an axis, said threaded member extending from the base and passing through said aperture; and means engaging said threaded member for holding said cover in place, said means having one generally flat surface from which a threaded bore extends, the remainder of the surface of said means being smooth and generally arcuate having no depressions or indentations, said means being positioned within said recess such that it may be approached only along the axis of said threaded member.
