1. A handheld tool for installing or removing a railway track fastener, said handheld tool comprising:
a drive assembly including an actuator sub-assembly mounted for actuation within an actuator housing, the drive assembly also including a jaw member mounted to the actuator housing and adapted to contact either a rail seat or the track fastener the actuator sub-assembly including an actuator shaft which actuates by rotation within the actuator housing;
a driven assembly including an actuated sub-assembly including i) a threaded coupling arranged to be engaged by the rotating actuator shaft, and ii) an adaptor sleeve mounted within the actuator housing and secured to the threaded coupling, said driven assembly operatively coupled to the actuator sub-assembly for longitudinal movement of the driven assembly relative to the drive assembly on actuation of the actuator sub-assembly, the driven assembly also including i) an actuated housing within which the actuated sub-assembly is housed, and ii) an opposing jaw member mounted to the actuated housing and adapted to contact either the track fastener or the rail seat whereby in operation the longitudinal movement of the driven relative to the drive assemblies effects closing of the opposing jaw members relative to one another for installing or removing the track fastener.
