The pneumatic torque wrench provides precise torque control with a repeatability of ± 5%, equipped with sensors and solenoid valve switches, achieving a repeatability of ± 2%. Pneumatic torque wrenches, with their small size, light weight, high output power per unit weight, can achieve high torque output, low reaction force, low environmental pollution, and low cost, are widely used in many fields such as aerospace, mining, petrochemical, railway, construction, heavy vehicle assembly and maintenance, heavy equipment loading and unloading, especially in product production assembly lines, especially in situations where high torque is required.

The operation of pneumatic torque wrenches is quiet - below 85dB (A), absolutely without impact, reducing damage to tools, sleeves, and locked objects. These two factors can make tool users comfortable to operate, reduce fatigue, and improve safety. The maximum torque can reach 300000 N. m.
