the Features of impact socket set

Although the concave shape of the impact socket set the same, but the outside diameter, length and other equipment for the corresponding shape and size of the design, the state is no uniform requirement, can be used with a wide range of torque wrenches with, so the impact of the sleeve design relatively flexible, to meet the needs of the public.
First, the use of advanced chrome - molybdenum steel, more resistant to wear, long life
Second, forging molding, reasonable hardness, high impact resistance
Third, through multiple heat treatment process, the organization is reasonable, uniform hardness
Fourth, high precision, reduce screw wear
