Ring wrenches
— keys with a working profile in the form of a ring, the inner part of which is in contact with the fastener when working (for this it is made in the form of a polyhedron or other corresponding figure). The main advantage of ring wrenches is high torque and minimal edge breakage, which makes it easier to work with tightly twisted, rusted and other “difficult” fasteners. On the other hand, the cap tool is not well suited for hard-to-reach places; and with hoses, pipelines and other similar elements fixed at both ends, such wrenches are not compatible at all.
