Abstract (en)
[origin: WO8604853A1] Power assisted wrenching tool (10) for the attachment of fasteners (42, 34) in loose and interference fit applications, and particularly for use with frangible fasteners (34). The improvement comprises a readily removable key (36) which is used to immobilize the bolt (42) during attachment of a threaded fastener (44), typically in a loose fit application. The key (36) is retained in the wrenching tool assembly by a detent ball (64) which is positively locked in the center core (48) of the holder member (38) of the wrenching tool and can only be disengaged by the axial alignment of the holder member (38) and the socket drive member (50) of this assembly. The tool is thus easily adaptable for the application of fastners in either loose or interference fit applications.
