Steel: 6140CrV 44-48 HRC Nickel-plating A: 35 mm; B: 23 mm; C1: 6 mm; C2: 11 mm; Length: 210 mm The classic version of a combination wrench with a open-ended profile on one side and a twelve-sided socket profile on the other. The combination wrench is the most common type of wrench as it combines the capabilities of an open-ended wrench and a socket wrench. The socket profile is offset from the longitudinal axis of the wrench body by 15°, allowing for work in limited spaces. The precision manufacturing of the twelve-sided socket profile minimizes the likelihood of rounding off the edges of fasteners. The open-ended part is inclined at a 15° angle relative to the longitudinal axis of the wrench body, allowing for a minimal angular step of 30° when working in tight spaces. You can also purchase combined wrench sets.
