The movable jaws being actuated with the vise screw. The loads on the vise screw from the jaws being reacted initially by springs that apply a resilient preload against a workpiece in either one of the movable jaws. One jaw is driven with a sleeve rotatably mounted on a cylindrical section of the vise screw and driven through a load release clutch. The springs are mounted on a vise screw support housing that is slidably mounted on the vise base and which provides automatic adjustment of the vise jaws to clamp different size workpieces in the jaws. The sleeve has a threaded section for operating one of the jaws.
