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 grooves 20 on the bolt. The jaws are openable to receive the projecting portion of the bolt 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 51 for detecting when the bolt 36 has been fully inserted into the open jaws 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 on the jaws correctly in relation to the grooves on the bolt to enable closure of the jaws. |
