The explosion-proof hexagon wrench is an L-shaped hexagonal rod wrench, which is specially used for turning the hexagon socket screw. The model of the Allen wrench is based on the size of the opposite side of the hexagon, and the size of the bolt has national standards. It is specially used for tightening or dismantling round nuts on machine tools, vehicles and mechanical equipment.
After the explosion-proof Allen wrench is formed, it undergoes high temperature bluing treatment. In the high content of sodium hydroxide and sodium nitrite solution, the temperature is above 140 degrees, and a dense oxide film (Fe2O3 and Fe3O4) is formed on the surface of the steel parts. There are different color differences, which have nothing to do with roughness; the bluing film is not resistant to corrosion, so it should be dipped in anti-rust oil after bluing.
The tensile strength of the processed beryllium bronze percussion wrench can reach more than 35 degrees, and the product of this material is both explosion-proof and anti-magnetic.
The aluminum bronze alloy products can reach more than 25 degrees, and according to the different needs of customers and friends, they can definitely meet the needs of customers and friends for percussion wrench products.
The percussion wrench is made of aluminum bronze alloy and beryllium bronze alloy as raw materials. The percussion wrench is processed through multiple processes. The surface treatment of the product has various situations for customers and friends to choose. Explosion-proof The surface treatment of tool products includes natural color, electrostatic spraying, etc.
