         3 . The anti-vibration fastener of  claim 2 , wherein the forward nut further comprises:
 a front portion, comprising:
 a front aperture disposed at substantially center portion of the front portion to receive at least a portion of the first threaded portion therein, the front aperture having a diameter substantially similar to the diameter of the first threaded portion, and 
 a plurality of internal threads disposed within an inner surface of the front aperture oriented in the first direction to correspond to and interweave with the plurality of external threads of the first threaded portion. 
   
     
     
         4 . The anti-vibration fastener of  claim 2 , wherein the forward nut further comprises:
 a stub portion connected to the front portion of the forward nut, the stub portion comprising:
 a rear aperture disposed at a substantially center portion of the stub portion to receive at least a portion of the second threaded portion, the rear aperture having a diameter substantially similar to the diameter of the second threaded portion, and 
 a plurality of internal threads disposed within the an inner surface of the rear aperture oriented in the first direction to correspond to and interweave with the plurality of external threads of the second threaded portion. 
   
     
     
         5 . The anti-vibration fastener of  claim 4 , wherein the stub portion further comprises:
 a plurality of external threads disposed on an external surface of the stub portion of the forward nut.   
     
     
         6 . The anti-vibration fastener of  claim 5 , wherein the aft nut further comprises:
 a front portion, comprising:
 a front aperture disposed at a portion of a center of the front portion to receive at least a portion of the stub portion of the forward nut and having a diameter substantially similar to the diameter of the stub portion of the forward nut, and 
 a plurality of internal threads disposed within the front aperture oriented in the first direction to interweave with the plurality of external threads disposed on the stub portion of the forward nut. 
   
     
     
         7 . The anti-vibration fastener of  claim 6 , wherein the aft nut further comprises:
 a stub portion, comprising:
 a rear aperture disposed at a portion of a center of the stub portion to receive at least a portion of the third section and having a diameter substantially similar to the diameter of the third section, and 
 a plurality of internal threads disposed within the rear aperture oriented in the at least one direction to interweave with the plurality of external threads on the third section. 
   
     
     
         8 . The anti-vibration fastener of  claim 1 , wherein the square flange bolt further comprises:
 a non-threaded portion disposed between the first threaded portion and the second threaded portion to separate the first threaded portion from the second threaded portion.   
     
     
         9 . An anti-vibration fastener, comprising:
 a square bolt to affix an object to a wall, the square bolt comprising:
 a first threaded portion having a first diameter, the first threaded portion being disposed at a front end of the square bolt, and 
 a second threaded portion having a second diameter, the second threaded portion being disposed at a rear end of the square bolt to be at least partially inserted into the wall; 
   a forward nut to encapsulate at least a portion of the square bolt such that the first object is disposed between the forward nut and the wall; and   an aft nut to encapsulate at least a portion of the square bolt and the forward nut.   
     
     
         10 . The anti-vibration fastener of claim  15 , wherein the second diameter is larger than the first diameter. 
     
     
         11 . The anti-vibration fastener of claim  15 , wherein the second diameter is smaller than the first diameter. 
     
     
         12 . The anti-vibration fastener of claim  15 , wherein the square flange bolt further comprises:
 a non-threaded portion disposed between the first threaded portion and the second threaded portion to separate the first threaded portion from the second threaded portion.
