It is suitable for use in car workshops, auto repair shops, and service centers, as well as for household use. - Made of chrome-vanadium steel using the hot stamping method at a reduced blank temperature. - The working profiles of the wrench are manufactured with increased precision and heat-treated to a hardness of 39-41 HRC. - It has a standard profile of the open end of the wrench, and an OVER DRIVE profile on the ring end. - The 15-degree tilt angle of the ring end relative to the plane of the wrench provides more convenient installation. - Wear-resistant and suitable for long-term use under maximum loads. - Protected from corrosion by a matte chrome-nickel coating. Thanks to the OVER DRIVE profile on the ring end of the wrench, the repair time of the car is significantly reduced.
