ABSTRACT:
The present invention is directed to a bond integrity tool, which includes a shoulder housing, a collar shaft, and an end cap. The collar shaft has a neck portion and a mouth portion. The neck portion is disposed within the shoulder housing, and the mouth portion is able to grip a test piece. The end cap communicates with the neck portion, such that when the end cap is initiated the end cap applies force on the shoulder housing, which in turn applies force on the collar shaft, which grips the test piece such that the bond integrity between the test piece and a surface may be tested.
