Steel: 6140CrV 44-48 HRC Nickel-plated A: 40 mm; B: 30 mm; C1: 8 mm; C2: 10 mm; Length: 230 mm The classic version of a combination wrench with a socket profile on one side and a twelve-sided open end profile on the other. The combination wrench is the most common type of wrench as it combines the capabilities of a socket and open end profiles. The open end profile is offset from the longitudinal axis of the wrench body by 15°, allowing for work in tight spaces. The precision manufacturing of the twelve-sided open end profile minimizes the likelihood of slipping off fastener edges. The angle of inclination of the socket 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 areas.
