Steel: 6140CrV 44-48 HRC Nickel plating Protective varnish A: 17 mm; B: 18 mm; C: 4 mm; Length: 120 mm A wrench with a classic socket profile. Socket wrenches are widely used for various tasks. This is due to the unique property of its open jaw: the ability to work when access to fasteners is possible only from one side. When working, the socket profile leaves the fastening element open for inspection. The angle of inclination of the socket part relative to the longitudinal axis of the wrench is 15°, which allows to achieve a minimum angular step when working in hard-to-reach places up to 30°. You can also buy a set of socket wrenches.
