A manually held hydraulically and pneumatically powered swaging tool for swaging a collar (35) onto a grooved or threaded bolt (36) includes jaws (39) having internal grooves (40) which match the groove (20) on the bolt. The jaws (39) are openable to receive the projecting portion of the bolt (36) and are closable to engage the bolt. An anvil (26) outside the jaws is axially movable by hydraulic means forwards over the jaws to lock them into engagement with the bolt, and then to force the anvil over the collar (35) to swage it to the bolt. The tool includes a detection rod (40) for detecting when the bolt (36) has been fully inserted into the open jaw (39). Thereby to initiate closure of the jaws by pneumatic means. Also, initial forwards movement of the anvil (26) is arranged to move the jaws axially forwards by an appropriate small distance, if this is necessary to axially align the grooves (40) on the jaws correctly in relation to the groove (20) on the bolt to enable closure of the jaws. |
