They are excellent for gripping, holding, pressing and bending applications. Zero backlash jaw surface pressure prevents damage to edges of sensitive and soft nuts. No unintentional shift of the gripping jaws and no slipping of the joint. Parallel jaws allow infinitely variable gripping of all widths to the specified maximum size. The action of the jaws allows bolted connections to be tightened and released quickly using the ratchet principle. Lever transmission greater than 10-1 for strong gripping power.
