Klein Tools wrench pliers. The main feature of this model is the parallel jaws. Unlike conventional pliers, where the jaws converge at an angle, here they remain parallel at any opening, you get a uniform grip on the entire surface of the nut or bolt. And now for the most interesting part - reversible jaws with notches. On one side you have the usual smooth surface for nuts and delicate parts, flip it over and you have aggressive notching for a firm grip on pipes and profiles. The lever on the handle allows you to change the grip size with just one movement, even in tight spaces. You have 20 adjustment positions and a maximum jaw opening of up to 2 inches - that covers most everyday tasks. Thanks to the clever design, these pliers give you amazing gripping power.
