ABSTRACT:
There is disclosed an improved power assisted wrenching tool for the attachment of fasteners in loose and interference fit applications, and particularly for use with frangible fasteners. The improvement comprises a readily removable key which is used to immobilize the bolt during attachment of a threaded fastener, typically in a loose fit application. The key is retained in a wrenching tool assembly by a detent ball which is positively locked in the center core of the holder member of the wrenching tool and can only be disengaged by the axial alignment of the holder and the socket drive members of this assembly. The tool is thus easily adaptable for the application of fasteners in either loose or interference fit applications.
