Steel: 6140CrV 44-48 HRC Nickel Plating A: 24 mm B: 37 mm Length: 235 mm The hinged combination wrench is an inseparable variant of a drive and extension with a hinged twelve-sided socket head (angle of inclination 180°). It combines the capabilities of a socket head and a socket profile. It is intended for efficient use and transmission of significant force when working in hard-to-reach places. Turning the socket head parallel to the body of the wrench allows for quick unscrewing and fastening of fasteners when no significant force is required. The socket profile allows for work with fasteners in cases where access to the fastener is possible only from one side. You can also buy sets of hinged combination wrenches: 516 061 and 516 091.
