The three things you should know about your torque wrench

Torque wrenches are common place across a number of industries. However, despite their widespread use, there remains a number of things that people get wrong or simply don’t know. This article highlights the top three things to consider.

Storing your torque wrench

When a torque wrench is in regular use it does not need to be wound back. However, when storing a torque wrench for an extended period of time, users should always wind it down to the minimum scale setting and never to zero.

A fully loaded torque wrench, left in storage for a long period, can cause a ‘set’ in the spring, causing it to weaken over time. On the other end of the scale, by completely off-loading the spring, other components within the wrench may move fractionally relative to each other. When you reapply spring compression the orientation of these components can change, therefore affecting accuracy. All in all, it is better to leave a bit of compression in the spring while in storage.

For accurate results, one click is enough

Users often allow torque wrenches to click multiple times, without being aware of the additional torque being applied to the bolts. Operate your torque wrench in a smooth and steady manner and remember that one click is enough.

Adjusting your torque wrench

Equipment manufacturers will always provide the required torque for any given piece of equipment and so when adjusting your torque wrench it is important to ensure that these levels are met. Remember to always adjust the wrench up the scale to the required torque figure to ensure accurate setting.

Keeping this advice in mind will see users getting more from their tool, with the wrenches becoming more accurate and lasting longer.
