Dual purpose wrench

One end of the dual-purpose wrench is the same as the single end solid wrench,and the other end is the same as the ring wrench.Both ends are twisted with the same specifications of bolts or nuts.The dual-purpose wrench is made of beryllium bronze or aluminum bronze alloy materials.

Scope of application of dual-purpose wrench:It can be widely used in potential fire and explosion hazardous environments such as petroleum,petrochemicals,oil stations,oil depots,gas production,chemicals,power,mines,electronics,railways,etc.It is also a tool for mechanical manufacturing and maintenance.The tensile strength of processed beryllium bronze products can reach 35 degrees or above,and this material can be anti magnetic,So this product is both anti magnetic and particularly suitable for use in demanding workplaces.The tensile strength of the aluminum bronze dual-purpose wrench can reach 25 degrees or more.Dual purpose wrenches are commonly used wrenches that undergo a series of inspections after processing in the machining workshop.

Appearance quality inspection of dual-purpose wrench:The surface of the wrench should not have cracks,burrs,obvious gaps,cuts,oxide skin and other defects,and the handle should be straight.

Dimensional inspection:The external dimensions of the wrench should comply with the relevant provisions of GB4388 and GB4389 standards.The opening of the wrench and the tolerance of the wrench hole should comply with the provisions of GB4390 standard.
