A universal vise that has a movable and a fixed jaw that can be indexed at 90 DEG increments to provide for four separate work clamping surfaces on each jaw. The vise includes a vise screw driving a nut that drives the movable jaw in each of four indexed positions of the movable jaw. The nut provides a down pressure load on the movable jaw with a very low profile. The indexable jaws permit the vise to be adapted to hold four different types of products or workpieces. The movable vise jaw is guided with keys that protrude above the plane of the guideway surfaces of the vise, so that the nut can have a shield rib that completely fills the space between the guideway surfaces to prevent chips from building up in a recess between the rails formed with present vise jaw nuts. The movable jaw and the fixed jaw do not protrude toward the base of the vise beyond the plane of the guideway surfaces on the vise rails. The movable jaw is held on the nut with a detent latch that permits changing of the jaw position when desired. |
