Ring wrenches

Union

— ring spanners have a working profile in the form of a ring, which, during operation, covers the nut or bolt head. This ensures the tightest contact with the fasteners, and the risk of tearing the edges is minimized. On the other hand, such wrenches are not applicable when working with pipelines, hoses and other similar items in which it is not possible to put the ring on the fastener. And in hard-to-reach places, when the bolt head or nut is deeply recessed, such a tool may be useless.
