1. Calibration

One common issue with torque wrenches is calibration. Over time, torque wrenches can lose their accuracy and may require recalibration. This can happen due to regular wear and tear, misuse, or improper storage. It is important to regularly check the calibration of your torque wrench and have it recalibrated if necessary. Professional calibration services are available, or you can purchase a torque wrench calibration kit to do it yourself.

2. Lubrication

Lack of proper lubrication can also cause issues with a torque wrench. Lubrication helps reduce friction and allows for smooth and accurate application of torque. If you notice that your torque wrench is not functioning as smoothly as before or if you hear any strange noises during operation, it may be a sign that the internal components need lubrication. Check the manufacturer’s instructions for the recommended lubrication and apply it accordingly.

3. Storage

Proper storage is essential to maintain the performance and accuracy of a torque wrench. Storing a torque wrench in a dusty or humid environment can lead to corrosion and damage to the internal mechanisms. It is important to clean and dry the torque wrench thoroughly after each use and store it in a clean and dry location. Avoid exposing the torque wrench to extreme temperatures or excessive vibration as well.

4. Overloading

Another issue that can occur with torque wrenches is overloading. Using a torque wrench beyond its rated capacity can cause damage to the tool and compromise its accuracy. Always ensure that you are using the correct torque wrench for the specific application and that you are applying the appropriate amount of torque. If you are unsure about the correct torque specifications, consult the manufacturer’s guidelines or a professional.

5. Impact Damage

Any impact or drop can potentially damage a torque wrench. Even a small impact can throw off the calibration and cause the tool to become inaccurate. It is important to handle a torque wrench with care and avoid any accidental drops or impacts. If a torque wrench has been dropped or impacted, it should be inspected for any visible damage and recalibrated if necessary.
