11 Expert Guidelines on Using and Maintaining a Torque Wrench

One of the most common tools found in the toolbox of race teams, engine builders, personal and professional garages, huge facilities etc., is the torque wrench tool. From fastening the bolts on an automobile engine to inspecting fastener tolerances on heavy-duty equipment, no matter the type of application, the torque wrench tool plays an important role.

However, its usage and maintenance is not given due importance many a time by the users. For instance, people often don’t have a clear picture regarding torque wrench calibration as well.

So to ensure that your device performs optimally and delivers precise results consistently, it is important that you know the do’s and don’ts of torque wrench calibration, and hire an accredited laboratory which offers professional calibration services.

So, here’s a list of 11 expert guidelines which will help you use and maintain your torque wrench tool flawlessly. Take a look –

  1. Manufacturer’s directions regarding proper force, torque direction, pattern, lubrication on fasteners and tightening or releasing cycles etc., should be followed without fail every time the torque wrench tool is used.
  2. The tool should never be used to break loose fasteners.
  3. The wrench should never be set at values higher or lower than those indicated on the scale.
  4. Use the wrench with great care. If it is dropped, it will lose its calibration.
  5. Do not under any circumstances use a torque wrench whose calibration certification has expired or is missing.
  6. Always store the wrench in its own storage case after cleaning and setting it at its lowest torque setting, when not in use.
  7. A cheater bar or any other type of extension should never be used to apply extra torque. Instead, use a larger torque wrench.
  8. If the rated torque of the tool is exceeded, it will cause over-torquing which eventually results in wrench or part failure.
  9. Check your tool’s calibration at regular intervals. Especially if the tool falls, is damaged or the environment conditions in which it is stored are altered; it is important to verify the tool’s calibration before using it.
  10. Do not disassemble or try to repair a torque wrench by yourself. The tool should be repaired and calibrated strictly as per the manufacturer’s instructions and by professionals so as to ensure that it continues delivering precise results.
  11. For best results, maintain your torque wrench by periodically calibrating it with help of professional calibration services of an accredited laboratory.
