Steel: 6140CrV 44-48 HRC Nickel plating A: 15 mm B: 23 mm Length: 175 mm The hinged combination wrench is a non-dismantlable version of a drive and extension with a hinged twelve-point socket head (180° tilt angle). It combines the capabilities of a socket head and an open-end profile. Designed for efficient use and transmission of significant force in hard-to-reach places. The rotation of the socket head parallel to the body of the wrench allows for quick loosening and tightening of fasteners when no excessive force is required. The open-end profile enables working with fasteners in cases where access is possible only from one side. You can also purchase sets of hinged combination wrenches 516 061 and 516 091.
