Query: Work very well

Since I am a mechanic I pay attention to how the wrench fits the flare nut. These fit very well and I was able to remove the old brake lines and torque the new ones (11 ft lbs) with no damage to the flare nuts using the 10 mm. Some areas were very difficult to torque, I was able to use the 12 MM with my 3/8 inch torque wrench and torque with the 10 mm. The wrenches are worth the price, I am totally satisfied.
