Excellent for gripping, holding, pressing and bending workpieces and for careful installation of components with delicate surfaces. The zero backlash jaw pressure prevents damage to edges. Fast adjustment by pushing a button directly on the workpiece. These pliers replace a complete set of spanners with their parallel jaws, which allow infinitely variable gripping of all widths to the specified maximum size. Screwed connections can be tightened and released quickly by using the ratchet principle. The lever transmission ratio is about 10:1 for strong gripping power.
