The adjustable wrench replaces a set of wrenches, both metric and imperial. The smooth jaws allow for gentle installation of surface-finished fittings and work directly on chrome. It is also excellent for gripping, holding, pressing, and bending workpieces. There is no edge damage to sensitive fittings due to the play-free, full-surface contact. The quick adjustment via a push button occurs directly on the workpiece. There is no unintended adjustment of the gripping jaws and no slipping of the joint. The stroke between the gripping jaws allows for quick tightening and loosening of screw connections using the ratchet principle. The high clamping force is achieved through a tenfold amplification of hand force. Capacities: half-moon, mm², connection square, square, step square, triangular, clamping range hexagon, clamping range round, clamping range square, span.
