Steel: 6140CrV 44-48 HRC Nickel-plating A: 35 mm; B: 25 mm; C1: 7 mm; C2: 10 mm; Length: 210 mm The classic version of a combination wrench with an open-end profile on one side and a twelve-pointed profile on the other. The combination wrench is the most common type of wrench as it combines the possibilities of both the open-end and the box-end profiles. The box-end profile is angled 15° away from the longitudinal axis of the wrench body, allowing for work in tight spaces. The precision manufacturing of the twelve-pointed profile minimizes the likelihood of slippage of the fastening edges. The angle of inclination of the open-end part relative to the longitudinal axis of the wrench body is 15°, allowing for a minimal angular step of 30° when working in hard-to-reach areas.
