Steel: 6140CrV 44-48 HRC Nickel-plating A: 43 mm; B: 30 mm; C1: 8 mm; C2: 13 mm; Length: 240 mm The classic version of a combination wrench with a box-end profile on one side and a twelve-sided profile on the other. The combination wrench is the most common type of wrench as it combines the capabilities of box-end and open-end profiles. The open-end profile is offset from the longitudinal axis of the wrench by 15°, allowing you to work in limited spaces. The precision manufacturing of the twelve-sided profile minimizes the likelihood of slipping off the edges of fasteners. The angle of inclination of the box-end part relative to the longitudinal axis of the wrench is 15°, allowing you to achieve a minimum angular step of 30° when working in difficult-to-access areas. You can also purchase sets of combination wrenches.
