A combination wrench made of extremely high-strength cold drop forged CRV tool steel. The key has undergone a careful heat treatment process. Hardened in a vacuum oven and cooled in oil, it prevents decarbonation on the surface of the key. Then it is tempered at the right temperature, which in turn reduces the stresses arising during hardening, and thus significantly greater bending strength of the key.
Perfectly protected against corrosion by nickel plating and matte satin coating.
The flat head set at an angle of 15 ° and the ring head bent by 15 ° make it easy to use the key and unscrew in hard-to-reach places.
