The ratchet handle wrench, which allows very fast adjustment, allows direct use without adjustment. Tightening and loosening is done without pulling the key nut. It prevents nut deformation and provides use in the removal of deformed nuts. It has a steel body reinforced with a convex surface profile to prevent deformation of the nuts, a special phosphate coating resistant to rust and impacts, and a rubber coated handle for comfortable use without fatigue.
