What is a torque wrench calibration?

Torque wrenches must work within strict tolerances to provide the right force to tighten bolts or nuts as required. A properly calibrated wrench will accurately measure torque, allowing a fastener to be tightened with the correct tension and preventing mutual connection failures.

What are hydraulic torque wrenches used for?

A hydraulic torque wrench is a device with calibration that can measure the torque applied to fasten and attain the desired tightness or loosen a bolt. It was invented by George A Sturdevant in 1968.

Why do torque wrenches need to be calibrated?

If your torque wrench has been improperly stored for long periods, it will need to be professionally re-calibrated to ensure torque values are accurate. Unfortunately, in some cases, your torque wrench may not be able to be adjusted back within manufacturer’s specifications and will need to be replaced.

Do all torque wrenches need to 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.

What are the two most common sources used to run hydraulic wrench pumps?

Hydraulic tool users can choose from three primary power sources: hand, electric, or air.

Can you calibrate your own torque wrench?

You can pay a professional testing lab to do the calibration, or you can assemble a torque wrench calibrator and do the testing yourself. To perform a torque wrench calibration on your own, you need to determine the calibration ratio and multiply that amount by the required bolt torque.

How often do you need to calibrate a torque wrench?

every 12 months
In short, it’s standard practice to calibrate your torque wrench every 5,000 cycles or every 12 months, whichever comes first.

How often should I calibrate my torque wrench?

If you’re looking for a straight answer, it is standard practice to calibrate your torque wrench every 5,000 cycles or every 12 months, whichever comes first. However, there is a lot more complications than a simple straight answer. First, if you are in a regulated industry, such as aviation, there is likely a set calibration date for you to follow.

Who calibrates torque wrenches?

GMS Instruments calibrates and certificates various types of torque wrenches such as digital torque wrenches, hydraulic torque wrenches, etc. with the best calibration tools available today. That’s why we have installed an all-new Gedore torque wrench calibration and certification bench to guarantee quality after calibration in 2020.

Where to get torque wrench calibrated?

For many companies, the best place to get a torque wrench calibrated is at a third-party calibration lab. The issue is that not every company meets every ISO standard for torque tools. Complicating the matter further, some calibration laboratories are limited in the types of torque tools they work with and the amount of torque they can test.

How accurate is torque wrench?

As a rule of thumb, torque wrenches are most accurate in the middle of their acceptable range and least accurate at the top and lowest 10\%. For example, if a wrench is rated for 10 ft-lbs to 100 ft-lbs, it’s least likely to be accurate below 19 ft-lbs and above 91 ft-lbs.
