Patent ID: 8398349

Claim:
A system for fastening a second object to a first object that resists unfastening until unlocked, said fastening system comprising: a. a girder having one end anchored to the first object, and another end having an externally threaded terminus also defining an internally counter-threaded axial bore; b. a cap having an essentially planar outer face and an internally threaded transplanar bore for rotational engagement with said terminus of said girder; and c. a counter-threaded bolt having a diameter smaller than said transplanar bore and a length sufficient to rotationally engage said axial bore of said girder while inserted through said transplanar bore; d. said cap planar outer face further including a pair of stops on opposite sides of said transplanar bore extending outwardly from the planer surface and; e. said bolt having a head cooperating with said stops for preventing substantial relative rotation of said bolt with said girder.
