I have had mechanics and one person who builds competition airplanes swear that torque wrenches are inaccurate when an extension is added. To me, this flies in the face of the Action, Equal and Opposite Reaction Law. Just wondering if anyone has seen any explanation for this widely accepted phenomenon.
I do quite a lot of my own maintenance to my vehicles and I consider recommended critical. I think about these claims every time I set my torque wrenches. I can see a possibility of error if a universal comes into play but with straight extensions I don't see it.
What's a socket extension and why would you want to use it in the first place?
Anyhow
I have simple quick way to find the answer to your question..
First tighten the bolt with your torque wrench,,
Then loosen and tighten again with the extension..
Use another torque wrench to measure each time the value..to be double sure
