Steel: 6140CrV 44-48 HRC Nickel-plating A: 28 mm; B: 20 mm; C1: 6 mm; C2: 9 mm; Length: 170 mm The classic version of the combination wrench with a socket 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 socket and ring profiles. The ring profile is offset from the longitudinal axis of the wrench by 15°, allowing for work in tight spaces. The precision manufacturing of the twelve-sided ring profile minimizes the likelihood of slipping off fastener edges. The angle of inclination of the socket portion relative to the longitudinal axis of the wrench is 15°, allowing for a minimum angular step of 30° when working in hard-to-reach places. You can also buy combined wrench sets.
