The box-end wrench is widely used for various tasks. This is explained by its unique feature of having an open jaw, allowing it to work in situations where access to fasteners is only possible from one side. When working, the box-end profile keeps the fastening element visible. The angle of the box-end part in relation to the longitudinal axis of the wrench is 15°, allowing for a minimum angular step of 30° when working in hard-to-reach areas. You can also purchase a set of box-end wrenches.
