Steel: 6140CrV 44-48 HRC Nickel-plating A: 48 mm; B: 34 mm; C1: 9 mm; C2: 13 mm; Length: 270 mm The classic version of a combination wrench with a box-end profile on one side and a hexagonal open-end profile on the other. The combination wrench is the most common type of wrench as it combines the capabilities of a box-end and open-end profiles. The open-end profile is offset from the longitudinal axis of the wrench by 15°, allowing for work in confined spaces. The precision of the twelve-point open-end profile minimizes the likelihood of rounding off fastener edges. The angle of inclination of the box-end part relative to the longitudinal axis of the wrench is 15°, allowing for a minimum angle step of 30° when working in hard-to-reach areas. You can also buy combination wrench sets.
