Abstract
A vise assembly which is able, with one single operation, to adapt to a nut and to lock into position with respect to the nut positioned between a pair compressing jaws. The locking function is readily releasible with a releasing device. Thus, with one direction of rotation of the vise assembly the vise assembly is adapted to conform and lockingly engage the nut and with an opposite direction of rotation, the vise assembly jaws automatically release upon activation of the releasing device.
