The time for submitting torque wrenches for inspection mainly depends on the number of times you use them. Most torque wrenches should be submitted for inspection after 5000 times of use. However, some manufacturers claim that their torque wrenches can pass 10000 times of anti fatigue tests. This is a case of different opinions.
In fact, there is no simple standard answer to this question because it depends on the use of torque wrench. Many factors, such as the frequency of use, the setting of the percentage of full scale torque, the habits of use and storage, and the environment, have a certain impact on the torque wrench. Another major factor is torque tolerance. There is a critical degree between torque and shearbolt assembly. For example, a helicopter assembly company verifies its torque wrench before each use, while an automobile factory often does not have such a complicated procedure or control degree.
Can torque wrenches that have not been used for a long time not be submitted for inspection? In fact, take the preset wrench as an example. The preset torque wrench mainly uses its internal elastic rod to drive the indicator to send out a vibration and click sound alarm. The flexible rod is aging if it is not used for a long time, so it is not necessary to submit it for inspection if it is not used for a long time. If it is not used for a long time, friends can submit it for inspection once a year.
If it is used very frequently and the inspection place is far away, you can buy a "torque wrench tester" for calibration. As long as the error does not exceed the industrial installation standard.
