ABSTRACT:
There is disclosed and shown an automatic nut installation and torquing system (10) connected with an automatic fastener installation machine (11) whereby a threaded nut (21) is automatically conveyed in proper orientation from a supply source to a final installed position on a threaded fastener (34); the installed nut (21) being at a selectively predetermined final torque value that is selectively variably and controllable without regard to the torque output of the torque motor (48) so long as the desired installed torque value of the nut (21) does not exceed the maximum torque deliverable by the torque motor (48). The variability and controllability of installed torque is accomplishable without any recalibration or readjustment of torque motor (48) to change its torque output.
