A quick set hydraulic work holding vise comprising an elongated stationary base plate member, a front stationary jaw fixed to the base plate member at a front end thereof and a rear jaw movable toward and away from the stationary jaw slidably movable along an elongated slide plate member supported for limited movement longitudinally. The slide member has an upwardly facing helical screw threaded channel and the movable jaw carries an interrupted worm screw interlocking device to interfit with the screw threads of the channel for locking the movable jaw longitudinally, which can then be locked against raising or skewing by tightening screw to compress the jaw on the slide plate member. A hydraulic piston is connected to the slide plate member for rapidly moving it and the movable jaw thereon to the gripping position.
