In our industry its incredibly important to implement the correct safe working procedures and implement a maintenance strategy for all equipment
Torque wrenches have been around for decades and are still the primary choice for providing an exact amount of force required for correct bolt tightening. It is due to their accuracy of high torque values, that they have gained incredible popularity over the years, but it is because of the high force they provide that it is imperative they’re used in the correct manner.
By ensuring users follow the correct procedure for usage and set up, it will provide the best results and ensure operator safety.
Here are 8 best practices to help improve safety and efficiency when using a torque wrench:
Know the recommended range: Recommended ranges are to protect the operator and torque wrench itself from injury and damage. Exceeding these recommended ranges increases the risk of unreliable results and even injury. On average, a torque wrench range is 20 to 100% of full scale and for electronic wrenches, that range is 10 -100%.
Don’t use extensions or adaptors: Using extensions or adaptors increases the risk of injury and causing damage the wrench by accidental inaccuracy. If there are no recommended extensions by the manufacturer, you must never use one.
One-click is enough: Users often click multiple times without being aware additional torque is being applied and this causes more force to be exerted than required, this risks damage to your wrench. Using the “one-click is enough” method allows you to achieve the desired torque accurately in a controlled manner.
Equipped storage: Always store your torque wrench in a protective case and follow manufacturers guidelines for storage to prevent damage to the spring, if stored for long periods of time.
An anticlockwise thread: Most torque wrenches will indicate the clockwise direction, so check the specification before using in an anti-clockwise direction to prevent losing torque control.
Calibrate correctly: If calibrated incorrectly or not at all, it can cause unknown torque values. Always know to inspect your tool prior to use and recalibrate your wrench at regular intervals, either on an annual basis or in-line with manufacturers guidelines.
Lock for safety: Always apply the adjustment lock before operating if the wrench is fitted with one. Many injuries happen when accidental and unintended changes to the wrench settings occur.
Protect yourself: Always wear the required Personal Protection Equipment (PPE) such as safety glasses to protect the eyes, and the correct work gloves to protect hands from injuries.
By simply following these 8 best practices you can improve your torque operations.
