A tool having a rotatable axially bored drive shaft for manipulating a fastener, such as a nut or bolt, is provided with retainer means for holding a removable, fastener-gripping socket in position on the shaft end while permitting an auxiliary non-rotatable tool shank to project through the axial bore and out the shaft end. The retainer means preferably comprises a circular steel spring structure fitted in the axial bore which urges a depressible socket-engaging button to project a short distance outwardly on a side surface of the shaft adjacent its end.
