This is perhaps the most scientific torque wrench test we have seen yet.

Are digital torque wrenches more accurate?

Electronic torque wrenches measure torque with a strain gauge. These wrenches are more expensive than their mechanical counterparts, but they’re also more accurate. The big advantage of electronic wrenches is that they record each torque measurement.

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.
