Steel: 6140CrV 44-48 HRC Nickel-plating A: 19 mm; B: 12 mm; C1: 4 mm; C2: 5 mm; Length: 110 mm The classic version of a combination wrench with a box-end profile on one side and a twelve-sided open-end profile on the other. Combined 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 body by 15°, allowing for work in confined spaces. The precision manufacturing of the twelve-sided open-end profile minimizes the risk of slippage on fasteners. The angle of inclination of the box-end portion relative to the longitudinal axis of the wrench body is 15°, allowing for a minimum angular step of 30° when working in hard-to-reach areas.
