How do you ensure torque wrench accuracy and safety?

1 Choose the right type

There are different types of torque wrenches, such as beam, click, dial, digital, and hydraulic. Each one has its own advantages and disadvantages, depending on the application, accuracy, durability, and ease of use. You should choose the type that suits your needs and preferences, and follow the manufacturer's instructions on how to operate and maintain it.

2 Calibrate regularly

Torque wrenches can lose their accuracy over time due to wear and tear, temperature changes, storage conditions, and improper use. To prevent this, you should calibrate your torque wrench regularly, preferably before each use or at least once a year. You can either use a calibration device or send it to a certified service center. You should also check the calibration certificate and expiration date of your torque wrench.

3 Use the correct setting

Before you use your torque wrench, you should consult the specifications of the fastener and the part you are working on. You should use the correct unit of measurement, such as foot-pounds or Newton-meters, and adjust the setting accordingly. You should also avoid exceeding the maximum or minimum torque range of your torque wrench, as this may damage the tool or the fastener.

4 Apply steady and even force

When you use your torque wrench, you should apply a steady and even force in the direction of the fastener. You should avoid jerking, twisting, or tilting the tool, as this may affect the accuracy and safety of the torque. You should also stop applying force as soon as you hear or feel the click, beep, or indicator of your torque wrench. Do not over-tighten or loosen the fastener after reaching the desired torque.

5 Store and handle with care

After you use your torque wrench, you should clean it and store it in a dry and cool place. You should also protect it from dust, moisture, corrosion, and impact. You should never use your torque wrench as a hammer, pry bar, or breaker bar, as this may damage the mechanism and calibration. You should also return your torque wrench to the lowest setting or zero position before storing it, unless otherwise specified by the manufacturer.

6 Inspect and replace if needed

Finally, you should inspect your torque wrench regularly for any signs of wear, damage, or malfunction. You should look for cracks, dents, bends, rust, dirt, or loose parts. You should also test the accuracy and functionality of your torque wrench before and after each use. If you notice any problems or defects, you should replace your torque wrench or have it repaired by a qualified technician.
