Abstract: A hand tool for setting multipieced fasteners such as lock bolts by application of a relative axial force and being fluid actuated by a piston-cylinder actuable along a first axis and having a removable cartridge type nose assembly for applying the axial setting force to the fastener along a second axis radially offset from the first axis such that the area immediately behind the nose assembly is essentially open and with the tool having a handle to be gripped by the operator and with a portion of the tool including the nose assembly being selectively rotatable about the first axis to facilitate use of the tool in various installation situations.

Abstract: A tool for setting a fastener which includes a pin having a plurality of grooves adapted to be gripped by a plurality of jaws in a nose assembly of the tool with the jaws being resiliently held in flexible pockets in a manner maintaining the jaws in a desired axial and radial alignment with each other and with the fastener grooves and with the jaws being selectively movable into and out of the pockets whereby manual insertion and replacement is facilitated.
