Do you need to reset torque wrench?
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.
How often does a torque wrench need to be calibrated?
every 5,000 cycles
In short, it’s standard practice to calibrate your torque wrench every 5,000 cycles or every 12 months, whichever comes first.
What setting should my torque wrench be on?
If you expect to store a torque wrench for more than a few weeks, always wind it down to the lowest scale setting (never to zero). Storing a fully loaded torque wrench can result in a set in the spring, weakening the spring over time.
How does a torque wrench lose calibration?
The torque wrench can even lose calibration when used with the utmost care. The spring or other internal mechanism can wear or loosen over time from normal usage. Because of this, it is important to check the calibration of your torque wrench often and calibrate it as necessary.
What is the lowest setting on a torque wrench?
For big wrenches (measuring in ft-lbs increments) the lowest setting is usually 20 ft-lbs. If, for some reason, you have a click-type torque wrench that goes all the way down to zero, leave the wrench set to 10 or 20 pounds.
Should you double click a torque wrench?
Double checking your torque is never a bad thing. By double clicking, you are allowing the fastener to rest for a second, then you are back at it to get the proper amount of torque there.
Can a torque wrench be calibrated?
While all torque wrenches will need to be calibrated regularly, you can prolong the life of each calibration by returning the setting of the torque wrench to zero after each time you use it.

Not only is the accuracy adversely affected by cheater bar tools, but also serious bodily injury may result. If you are using a wrench extension bar that is vertical to the drive, it has no affect on the accuracy.
Why we need to calibrate a torque wrench?
A properly calibrated wrench will accurately measure torque, allowing a fastener to be tightened with the correct tension and preventing mutual connection failures. An excessive deviation can result in less reliable or vulnerable bolt connections.
What do you do with a torque wrench?
There are some models of torque wrenches that have double-ended drives that you can use for loosening and tightening. Position the wrench on the bolt and nut and start making adjustments. Many models have a beep or light that will go off when you’ve hit the desired torque level.
Why does my torque wrench not click when I swing?
See if you can get a click out of it that way. It could be the fastener is over tightened in the first place and it is clicking away without you noticing it at the beginning of the swing. If it still doesn’t click, you’ll need a new torque wrench.
What does the green light on a torque wrench mean?
On many digital wrenches, a light or buzzer will go off when you need to stop applying torque. Check your reading. Most digital wrenches will utilize a green light to tell you that the proper torque level has been reached. A red light will indicate if the torque isn’t within the right torque level.
