In this educational video we explore the threaded fastener, its relationship to torque, and fastener strength. What is torque? How is it measured? What loads and forces are at play within a bolted joint. How do we achieve clamp force? All these questions and more are covered in part 1 of Flexible Assembly Systems fastening theory video series. See below for a breakdown of the topics covered in this video.
The Threaded Fastener - 0:12
Fastener Strength - 1:00
4 Phases of Tightening - 1:49
What is Torque - 2:25

Torque & Clamp Force - 5:04 - Наука та технологія
Excellent video. This is the clearest short overview of torque in relation to clamping force that I have found so far on UA-cam. Looking forward to Part 2.
Thank you! That was our goal :) We are very glad you enjoyed it.
i can't believe it,,,,,,,,,this is the FIRST video i have ever seen with NO negative comments and i must add my POSITIVE comment to this list too. in part 2 i hope you will cover the importance of an accurate torque wrench and the correct way to come up to the final torque on a bolt..........i have torqued bolts on many diesel engines for a lot of years and always tried to be as accurate as possible. so this video was extremely interesting to me ..........thanks very much for a GREAT video.
Thank you! We plan on creating more videos that cover a wide range of fastening theory topics.
Thanks so much, this is just what I needed. I looked every where and wiki only offered text definition of Newton Meter Nm but this picture is much easier to understand for a person with no related learning background like me...
Great video thanks
This is really a well done video with a great short general explanation. Do you mind if it is used in a training environment?
Thank you! Yes, feel free to use this video as an example for training.
do a video on rundown torque thanks and how to calculate it?
Nice explanation
Where's part 2
We are working on it! A lot has been happening here at Flexible, but we will be rolling out the next video in this series in February!
Thanks for these videos. Good explanation of torque, and part 2 really puts the concepts into perspective.
Why am I binge watch vids on the theory behind screws lol
Because we all need to know how the world is kept together. The secret is clamp load ;)
Plz solve some problems on torque.for better understanding.
Knowledgeable video.great thanks
The door torque example is clever)
Thank you! I figure everyone has tried at least once to open a door from the "wrong side" and realized how much more force it would have required! It is definitely a good demo of how a longer moment arm creates more mechanical advantage!
Brilliant video, thanks !!
Excellent video for beginners
Thank you!
Fastenating!
Can you do a video on how to do torque math.
Things like added and subtracted lengths and the
real fun one of offsets and explain why a 90º offset
does not change the torque applied to a bolt.
Thanks for the good ideas, I will try to work these into the next video :D
I had an instructor in my helicopter portion of my A&P schooling that did a good job
of explaining it. I must say I was glad to have him because he would make you do the most
you that you could do by pushing you to give your best. I really liked that.
fantastic, i learnt so much
how can i fix the length of the movement arm arm
To change the length of the moment arm you would need a longer "handle" in the case of a torque wrench. The farther away the force is from the object you are trying to rotate, the longer the moment arm is.
Super video, many thanks.
What does a torque wrench check- tensile force, twisting force or compression force applied to a nut or bolt?
A torque wrench is usually a device that is able to rundown a fastener to a pre-calibrated torque value. Standard torque wrenches cannot measure force, they use a spring or mechanical mechanism to apply the torque until a certain point. Fancy torque wrenches with transducers such as the Atlas Copco ST Wrench are able to measure applied torque and angle, measure residual torque and more. In order to measure compression force (or clamp load) you would need to use a force gauge between the mating surfaces being fastened together. Tensile force would be measure in a plastic/elastic deformation strain test or something similar.
WHERE IS PART 2???
We are working hard on it now! It will take some more time for us to do all the animations :)
