ABSTRACT:
A fastener thread cleaning apparatus includes a first arm and a second arm each having a first end and a second end. The first and second arms are pivotally coupled together adjacent to the first ends to define a pair of jaws. An abutting side of each of the of the first and second arms is defined and abut each other when the pair of jaws is positioned in the closed position. Each of the of the abutting sides has a semi-circular depression therein. The depressions are alignable to define an aperture, which is threaded. The pair of jaws may be closed around a bolt to threadably engage the bolt with the aperture. The pair of jaws is positioned between a head and an end of the bolt and the bolt rotated to move the pair of jaws toward the end of the bolt.
