Abstract: An anti-loosening fastener, including a key-bolt-receiving bolt, including a head section to receive at least one tool thereon, a rear cylindrical section disposed on at least a portion of the head section to extend a predetermined distance away from the head section, the rear cylindrical section including a key-bolt-receiving aperture disposed within at least a portion of the rear cylindrical section to receive an external fastener therein, and an internal thread section circumferentially disposed on an inner surface within the key-bolt-receiving aperture, and a key bolt to removably connect to at least a portion of the key-bolt-receiving bolt.

Abstract: An anti-vibration fastener, including a square flange bolt to affix a first object to a second object, the square flange bolt including a first threaded portion disposed at a front end of the square flange bolt, and a second threaded portion disposed at a rear end of the square flange bolt having a diameter smaller than a diameter of the first threaded portion, and a forward nut to encapsulate at least a portion of the square flange bolt such that the first object and the second object are disposed between the forward nut and the front end of the square flange bolt, and an aft nut to encapsulate at least a portion of the square flange bolt and the forward nut.
