Air powered nut runner
摘要:
An air driven nut rotation device to rapidly advance a nut along a threaded rod. An apertured engagement disk is registerable about a nut threadably positioned on a rod. A plurality of radially positioned drive arms extend from said disk providing multiple spaced air impingement surfaces which when driven by a stream of air rapidly rotate the disk and nut engaged thereby advancing it along the threaded shaft in selected directional rotation depending on airstream directional engagement.
