Steel: 6140CrV 44-48 HRC Nickel plating Protective lacquer A: 18 mm; B: 22 mm; C: 5 mm; Length: 120 mm A wrench with a classic open-end profile. The open-end wrench is widely used for various types of work. This is due to its unique feature of being able to work when access to fasteners is only possible from one side. When working, the open-end profile leaves the fastening element exposed for better visibility. The angle of inclination of the open-end part relative to the longitudinal axis of the wrench is 15°, which allows for a minimum angular step of up to 30° when working in hard-to-reach areas. You can also purchase a set of open-end wrenches.
