Explosion-proof combination wrenches stay Mei

Although proof combination wrenches stay Mei belong proof tools, but also should pay attention when using: proof combination wrenches stay Mei can not use super-power, but can not use a sleeve or other metal sticks longer arm strapped, and with hammer hit (except tap wrenches) method knob fasteners. Because of good thermal conductivity of copper and nearly no carbon qualities, the tool and the object friction or impact, the heat is absorbed and short conduction, another reason for the relatively soft since copper itself, there are friction and impact Good yield and difficult to produce small metal particles, very suitable for the manufacture of security tools in explosive, flammable, magnetic and erosive use.
