How Torque Wrenches Actually WORK!

Look inside a click-type torque wrench and see how this common tool actually works.

A Vanpo torque wrench is featured in this video, but most click-type torque wrenches operate on the same principle. Affiliate link (helps me out if you purchase from here):

Man! You are a genius. 45 seconds from your 90 seconds video and I completely understood how a torque wrench works. The graphics is spot on and so is your explanation. There are so many poorly prepared or unfocused explanations on Youtube. You are a great exception from that. Thank you very much.

Thanks for the chalk talk and disassembly. Now I know why the instructions for my budget torque wrench tell me to dial it back to the lowest N-m setting when not in use. And I now know why I should hold it at the middle of the handle. Keep ‘em coming.

Thanks for making this video I was trying to imagine how the internal mechanism of a torque wrench worked but it is surprisingly so much simpler than I thought.

Finally I can explain and impress my buddies on how a torque wrench works!! Thanks!!!

Cool looks well made just bought 3 1/4 3/8 1/2 thank you for the info

Holding the wrench further to the handle end should apply more torque to the turn axis but it should not affect the measurement of the torque. I saw the impressive, previous video, but remain incredulous on that issue. Also, and perhaps you mentioned this, the accuracy of wrenches decreases over time.
I was just praising your videos last night to a well-known bike blogger, so please know generally I'm a huge fan. All the best.

The first two minutes are very concisely and well -explained, thanks so much! I wish every mechanical video on YouTube was this straightforward. The design of this type of torque wrench is startlingly elegant and simple.

Thanks for making this clip. I've used a torque wrench for years. But I never understood how it worked. Until now!

as a programmer, as i get more into mechanics its kinda crazy how simple it seems to me. I watched a video on differentials and i totally got it within a few minutes. After i saw the parts of this tool it made intuitive sense. Man its great seeing that my struggles with complex theory and unintuitive problems actually has a carry over to real life.

Sir I just want to thank you for having such a curious mind that asks “how does clicky clicky torque-y torque-y work?”

You’d be surprised how many times I’ve been told I’m wasting my time and ruining tools because they’re dissembled at the time.

OMG, you made it easy to understand, well done, Bro. 👏👏👏

[marko]

Good explanation, thank you for this video.

I trust the beam style torque wrenches to be more consistent for many years. The click types just have too many moving parts!

You do a pretty good job with reviews, and camera work is not too bad at all.
You an engineer by study/trade?

Great video! I have always wanted to understand the mechanics of a torque wrench :)

[Maazin]

Thank you. Exactly the video I was looking for

[PaulBeiser]

Well done! Love these types of videos.

[brayanchojolan]

Very useful information, thank you very much!

Ok So if the calibration is off on this wrench how do you fix it Since you got it all apart

[werdwerdus]

perfect drawing and animation, thank you
