Abstract

An improved control system usable with a spanner to control the tightening of a fastener, said system comprising: first means for periodically generating a signal representative of the instantaneous moment applied to the fastener; and control means responsive to said instantaneous moment signals to determine when an instantaneous moment signal has not increased more than a predetermined amount and to generate a control signal.
