Abstract
A system for fastening a first object to one or more other objects that prevents unfastening due to vibration until unlocked. The locking system includes: (a) girder having a first end that has an externally threaded terminus defining an internally counter-threaded bore; (b) a nut having an essentially planar top surface and an internally threaded bore for rotational engagement with the terminus of the girder, wherein the essentially planar top surface comprises at least two notches on opposite sides of the threaded bore of the nut; and (c) a counter-threaded bolt having a diameter smaller than the bore of the nut and a length sufficient to rotationally engage the bore of said girder while inserted through the bore of the girder, wherein the bolt comprises a head cooperating with the at least two notches for preventing substantial relative rotation of the bolt with the girder.
