Adjustable tightening tool. Also excellent for gripping, holding, pressing and bending workpieces. Replaces the need for sets of metric and imperial spanners. Smooth jaws for damage free installation of plated fittings. Zero backlash jaw pressure prevents damage to edges of sensitive components. Adjustment at the touch of a button directly on the workpiece. Parallel jaws give a more solid grip- the construction gives infinite adjustment of all widths up to the specified maximum size. Reliable catching of the hinge bolt: no unintentional shifting. The action of the jaws allows quick tightening and release of bolted connections using the ratchet principle. Lever transmission greater than 10 : 1 for strong gripping power. Chrome vanadium electric steel, forged, oil-hardened. With narrow gripping jaws - for tightening situations that require a slim tool.
