Steel: 6140CrV 44-48 HRC Nickel-plating A: 20 mm; B: 13 mm; C1: 5 mm; C2: 6 mm; Length: 120 mm The classical version of a combination wrench with a box-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 a box-end and an open-end profile. The open-end profile is offset from the longitudinal axis of the wrench by 15°, allowing work in confined spaces. The precision manufacturing of the twelve-sided profile minimizes the likelihood of slipping on the edges of fasteners. The angle of incline of the box-end part relative to the longitudinal axis of the wrench is 15°, allowing for a minimal angular step of up to 30° when working in hard-to-reach places.
