Product Description The combined wrench AUTODELO from the "Professional" series is used for working with fasteners during car repairs. It is suitable for use in auto workshops, car services, and vehicle inspection centers, as well as for household use. - Made from chrome-vanadium steel using the hot stamping method at a reduced temperature of the billet. - 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 for the open part of the wrench, and an OVER DRIVE profile for the ring part. - The 15-degree angle of the ring end relative to the plane of the wrench provides a more comfortable 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 part of the wrench, the repair time of the car is significantly reduced. The "Professional" series wrench is well suited for working with undamaged fasteners, as well as with fasteners that have burrs, bites, and other damages.
