Steel: 6140CrV 44-48 HRC Nickel plating A: 19 mm B: 28.5 mm Length: 210 mm The hinged combination wrench is a non-detachable option of a drive and an extender with a hinged twelve-sided socket head (180° tilt angle). It combines the possibilities of a socket head and an open-ended profile. It is designed for efficient use and transmission of significant force in hard-to-reach areas. The rotation of the socket head parallel to the body of the wrench allows for quick loosening and tightening of fasteners when applying less force. The open-ended profile allows you to work with fasteners in cases where access to the fastener is only possible from one side. You can also purchase sets of hinged combination wrenches 516 061 and 516 091.
