The present invention relates broadly to a handheld tool (10) for installing or removing a railway track fastener (12) in the form of an e-clip. The handheld tool (10) generally comprises a drive assembly (24) including an actuator sub-assembly (26), and a driven assembly (28) including an actuated sub-assembly (30) operatively coupled to the actuator sub-assembly (26). The actuator sub-assembly (26) actuates by rotation under the influence of an impact wrench (not shown) effecting longitudinal movement of the driven assembly (28). The drive assembly (24) further includes a jaw member (36) mounted to a bracket (38) extending from an actuator housing (34) of the drive assembly (24). The driven assembly (28) includes an actuated housing (40) within which the actuated sub-assembly (30) is housed. The driven assembly (28) further includes an opposing jaw member (42) mounted to an opposing bracket (44) extending from the actuated housing (40). In operation, the longitudinal movement of the driven assembly (28) relative to the drive assembly (24) effects closing of the opposing jaw members (36) and (42) relative to one another for installing or removing the e-clip fastener (12).
