Steel: 6140CrV 44-48 HRC Nickel plating A: 51 mm; B: 36 mm; C1: 9 mm; C2: 14 mm; Length: 280 mm The classic version of a combination wrench with a box profile on one side and a twelve-sided ring profile on the other. The combination wrench is the most common type of wrench as it combines the capabilities of the box and ring profiles. The ring profile is offset from the longitudinal axis of the wrench body by 15°, allowing work in confined spaces. The precision manufacturing of the twelve-sided ring profile minimizes the likelihood of slipping off the edges of fasteners. The inclination angle of the box part 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 places.
