How a torque wrench works

In this 3D animated video, we'll see how to use a ratcheting click-type torque wrench and look at the mechanism inside to see how it works. Click-type torque wrenches are the most commonly used type of torque wrench available.

A torque wrench is a specialized socket wrench tool designed to tighten fasteners to a predetermined torque value, ensuring consistency and preventing over or under-tightening of the fasteners, which can lead to issues like stripped threads or loosening.

I love how they used an 11mm socket, even here the 10mm went missing

He's using an 11mm socket because we know what happened.

Beautiful video. Your explanations are so clear and concise!

I use torque wrenches every day at work, and have been using them even longer in my hobbies at home. I’ve even been to a technical college where we learned our profession in depth, and indeed learned that a spring is compressed to set the desired torque value. Yet, no one could ever satisfactorily explain how the linear spring compression was translated to rotational torque measurement. In 5 minutes, you have solved a decades long mystery for me! Thank you.

Thanks for mentioning that you should store your torque wrench at the lowest SETTING. I have to constantly inspect my friends’ work when they put away my torque wrenches to make sure they didn’t leave it where it was or bring it all the way down past the lowest setting.

This channel is the very definition of underrated! Your videos are always super high quality and very accurately modeled, down to the tiniest of details.

I swear teachers all over the world should be legally obligated to use your videos, the quality all around is absolutely superb, I literally don’t have one single question about torque wrenches now and for me that is a rare thing with my A.D.D and overthinking, I wish I had you as a teacher my whole life with how clearly you explained every detail and how you were literal through the whole thing leaving no space for confusion

Been using click style torque wrenches for decades and always wondered how it worked inside and how the "click" was created. Perfectly edited computer graphics

[truthsmiles]

If you’ve never used a torque wrench before, it’s useful to understand the “click” is very subtle and easy to miss at low torque settings. It’s a good idea to practice with it to get a feel for how it works at different settings before tightening critical fasteners you don’t want to snap!

I don’t have anything to add, I just appreciate the no frills, straightforward, educational content. Engagement++

[MichalBrat]

I think the torque wrench is one of the most ingenious tools out there.

Great animation. If you keep 4 fingers’ distance away from the mic, the proximity effect will be reduced, and the levels after audio compression will be much easier to listen back to. It’s the difference between talking directly in someone’s ear and talking to them from an adjacent table chair.

Thanks for the work and that wonderful explanation!

As a kid I used to love those books that showed you internal diagrams of buildings, machines, etc. this channel is basically that in video form. ❤

[Ammotive]

I’m an engineer with an inquisitive mind. Used various torque wrenches thousands of times. It’s one of the very few things I don’t thinking I’ve ever stopped and asked “how does that work?”
So thanks

[sMtX]

I'm amazed at the detailed quality animations, that had to take so much time to properly model everything and animate. Great job, very educational.

[dixieduffy]

I use these all the time for work but had no clear idea how they worked. This sums it up fantastically.

[DanniV]

I've been working with these for over 20 years and have always wondered how exactly they worked. Never wondered hard enough to actually find out tho, so I always just chucked it up to being made by wizards and never questioned that reasoning. Today I was proven wrong.

[Weeblicker]

Whoever made this tool might be one of the most important humans to ever exist

[syazwanmurad]

I've been thinking how this tool works since forever, but always forgot to do the research. Suddenly, this video came across. Thank you for the explanation.

[dariusb]

Didn't expect such a concise explanation on such a seemingly trivial everyday object. Great video!
