ABSTRACT:
A tactile engaging wrenching tool adapted for use in the installation of blind bolt fasteners. The wrenching tool includes a wrench adaptor for engaging the fastener screw and a nose-piece for holding the fastener head while the screw is turned to set the fastener. A clutch assembly is provided which transmits a light torque load to the wrench adaptor while the nose-piece is engaging the nut head. The clutch assembly is designed to provide a high torque load to the wrench adaptor to turn the screw and seat the fastener only after the nose-piece has been biased into a secure engagement with the fastener. The wrenching tool mechanism is especially well-suited for use in systems for automatic installation of blind bolt fasteners.
