Tap wrench made of high quality carbon steel or high-quality steel forging from the overall, applicable to the petroleum, chemical, metallurgy, power generation, oil refining, shipbuilding, petrochemical and other industries.
Tap wrench has a reasonable design, stable structure, high material density, strong anti-strike capability, not off, constantly, bend, high dimensional accuracy, durability and other characteristics.

Explosion tap wrench is a security tool that effectively prevents sparks when working, for all flammable and explosive. His material is divided into two kinds of aluminum bronze and beryllium. These two materials from color component aluminum Bronze is yellow, red and yellow Beryllium is from HRC25 hardness of aluminum bronze and beryllium bronze stars HRC35. two materials have the same explosion-proof product features, beryllium copper products are magnetically shielded function, so the requirements for the work environment more stringent workplace is particularly suitable for use.
Explosion tap wrench products particularity lies in its particularity supply of places, because explosive workplace safety requirements for a high level, so in the petroleum, chemical, gas, gas, electrical, mining, etc. industry product particularly suitable for use explosion-proof wrench for routine inspection and maintenance of high neck tap wrench curved handle tap wrench convex tap wrenches
