ABSTRACT:
A tamper-proof or security threaded fastener assembly adapted for use with standard size bolts and screws is provided to reduce or eliminate the unauthorized removal of threaded fasteners from their desired position of fixation. A cap portion is adapted to completely encase the head of the bolt or screw such that, after tightening of the bolt or screw, access thereto is restricted to a special non-standard tool. In one embodiment, a nut portion is provided comprising an elongate strip provided with a threaded hole to receive the bolt and a perpendicularly disposed flange. An additional hole appropriately provided in the base or plate through which the bolt is attached is adapted to receive the flange of the nut portion in a manner which prevents the nut portion from being rotated after the bolt is tightened and fully drawn up to the base or plate.
