You are a great teacher, I like how easy it is to understand what you are explaining, It doesn't even matter that english is not my first language. Thanks for sharing your knowledge
Sorry to be offtopic but does someone know of a method to log back into an instagram account?? I stupidly lost my login password. I would love any help you can give me
@Carmelo Hank thanks for your reply. I got to the site through google and Im in the hacking process now. I see it takes quite some time so I will get back to you later with my results.
Fantastic video! I learned exactly what I was looking to learn. I think for a lay man this would be a little difficult to follow because of how fast paced it is and how many technical terms there are being used, not to mention a bit of math that can makes some peoples heads spin. However, for someone like me that has taken physics at the college level and just wanted to know more about what I've already learned it was easy to understand. I found your video simply because I was wondering why torquing bicycle parts to the correct specification was so important. I can now visualize problems that can go wrong when too much tension is applied while riding due to incorrect torquing of the bolts because of the way you explained the concept of bolts stretching. I never knew that they did this. Thank you again.
I agree! It is easy to understand and I also just wanted to understand torque importance in rebuilding engines and I understand now exactly what it is. Great video!
Great video. I really learned something. And by the way the comments about teachers in school teaching. Not all of them are bad plus the students probably aren't listening or paying attention. Put some blame on yourself.
Good info, but i am working on a 1976 pontiac,, the bolt are not graded in any way i can see, so then what are the torque values per diameter size? Is there a less than grade 1 which is why they are not marked? Not talking about engine bolts.
so once you know the torque specification do you apply that torque until the bolt stops turning? until its snug? how do you know when exactly to stop pushing? do you push until you can't push any more?
Yes! ^^^this. I have been a mechanic for about 20 years, but I was watching this video because of this concept. The axle nut on my motorcycle is a fine example. It is a castle nut, meaning there are notches in the top of the fastener that line up with a hole in the axle for the clevis pin, to prevent it from coming loose. The spec calls for 72 ft. lbs. However if I apply gentle pressure the nut will continue turning without clicking my torque wrench for another 1/2 turn or so. So at what point is the bolt properly stretched? When you first hit the proper torque.....or when proper torque is acheived and the nut also will no longer turn? In the past, I have torqued to spec, ajd just continued to rotate until the nearest hole is aligned with the nearest notch on the castle nut. I figured its better to be just a small margin too tight than having it too loose.
First you set the torque wrench. Then you tighten the bolt and once you get NEAR the required torque, you smoothly continue to tighten until the torque wrench indicates that you have reached the specified setting.
You have to turn the torque wrench smoothly and recheck and see if it turns if it turns keep turning it slowly until it stops, and do it again until it clicks without moving. Torque wrench needs some practice to get it right and the best way is to do that on a torque calibration tool and see how much torque you get comparing to your expectation, I always thought that I was doing it right until I did it on the machine, but after a few try I can get it consistent.
can u help me with the answer or formula A torque is applied on a nut of 1000 ft pound the nut is been moved 120 deg what is the total torque applied to the nut
Great info, just for clarification. If I have to tighten an bolt to 7.4 ft•ibf and I have a 2 foot torque wrench I have to multiply 2x7.4 to make sure it’s done correctly? The torque being 14.8 as opposed to setting the amount for 7.4? Or should I be setting the torque at 3.7 and the 2ft from the wrench supplies it to be 7.4 ft? I’m sorry if I am completely off.
When I see this type of torque value: 13-16 ft-lbs torque; I dont quite understand what it means--Does it mean find the in between or is that lubed/dry? I've been online for hours and still havent found the right answer~
+TheEye22 That means the torque spec is anywhere between 13 to 16 ft.lbs. of torque. So I would apply 15 ft.lbs. of torque. Lubed or Dry? Good question, but one that can ONLY be answered by the manufacturer of the product that you are torquing. And lube DOES make a difference, quite a bit in fact. So its very important to find out from the manufacturer how they do the torque specs, wet or dry.
He is wrong about fine threads "needing more torque owing to friction". That is not the case. Fine threads can handle higher clamping force because they are stronger, and they also develop more clamping force for a given application of torque owing to their finer pitch.
First of all,I like ur videos, but I have this torque chart I printed off the internet and it says 1ftlb =1.36nm and u said 1ftlb =14.6nm ,which one is right
homeystar77 your right. Technically torque is measured in pound-feet, foot-pound is a measurement of work. However the mistake has been made so often that it is widely accepted to just call torque measurements foot-pounds.
+tech270154 Using Anti-seize on a fastener is similar to using any type of lubricant. Using a lube on a bolt dramatically increases the clamping load, so it should never be used unless specified by the manufacturer.
Yeah, but we're talkin' British cars, here. I thought torque specs had to do with the weight of the mechanic and the length of the breaker bar. Wellp …learn somethin' every day, I reckon.
You don't meassure WEIGHT in Newton. You meassure FORCE. Weight is a directional force that depends on your location (even on earth). Weight would not have any meaning for torque.
Want a funny little reality. Go to Autozone and get a torque wrench. It is there that you will see a wrench whose measurements are engraved in increments based on 5. The dial however, to adjust between those increments are based on 6, thus a dial at a full turn that reflects that of 12 lbs, not 10, as so would be expected by the engraved markings. American quality at its finest. Wanna see what I mean? Go to 159. Most people would got to 160, then back off one lb. But if you go from the 0 on the dial, your at 161 from the 150 line, not 159. Fucking crap.
Nice video, but you made an error. You said "1 Nm equals 14.6 ft.lbs." Oh no, that's way, way off. Actually, 1 Nm equals 1.35 ft.lbs. Just do a correction graphic overlay on your video. Other than that, nice job. Gary @ Snap-on Tools.
Did I hear you right??? You are decimalising the imperial system, that's not logical. It makes no sense to say "point five feet", isn't that inches are for. Why not just cut your losses and metricate.
You are a great teacher, I like how easy it is to understand what you are explaining, It doesn't even matter that english is not my first language. Thanks for sharing your knowledge
Great video. I love in depth explanations of seemingly simple things. Thank you
When you listen to this person teach it reminds me of how terrible some of my teachers at school were at teaching,this man knows how to teach.
Great video, you explain it so well! I only had to watch this video to understand torque on bolts.
You should teach teachers how to teach.
Thanks for this lovely video lesson!

@Carmelo Hank it did the trick and I actually got access to my account again. I'm so happy!
Thanks so much, you saved my ass :D
@Ralph Kai glad I could help xD
Thanks I have wondered about these specifications for years.
Super video! Thoroughly understand what it really means to torque a bolt. Thank You!
great video. You have a natural ability to explain things very well. Please keep the videos coming
Amazing video, it explains everything I was looking for. Thanks a lot
I wish my High School teachers explained things like this. I would have aced the class.

Great video, helped me explain this to my friend.
Great vid, explained things well. Answered all my questions
Brilliantly explained
Thank you.
Awesome video. Very helpful and interesting to watch.
Excellent explanation. Thank you!
Amazing and very useful video.
Thanks.
What a great video Sir! Good job..
VERY INFORMATIVE, THANKS FOR YOUR TIME.
awesome i love these videos thanks for making another one
Great video. I really learned something.
And by the way the comments about teachers in school teaching. Not all of them are bad plus the students probably aren't listening or paying attention. Put some blame on yourself.
Very helpful.
Lots of thanks, and Salaam.
Can u help mi with the specific torque for 1HZ main bearing,conrod bearing and cylinder head??

Wow, feel like I just graduated from college!
Bottom crown fixing screws 6±1 , what would this be in NM ? This is the torque setting for my bike forks .
what is the torque settings for head bolts on a 09 Dodge Challenger
What is the torque for toyota corolla 2e cylinder head bolts?
Would you know the specification torque for a 2015 nissan versa Rear Hub Axle Nut?
Thank you for a great video!!!
Anyone know what 25 ± 5 N·m would be? or is it just 25.5 Nm...

Sir please share one more vedio by unit of newton mitar
beautiful. thank you.
Thank you!
First of all,I like ur videos, but I have this torque chart I printed off the internet and it says 1ftlb =1.36nm and u said 1ftlb =14.6nm ,which one is right
What about engine torque?
What this mean when it tells you to torque it to 15 to 30 lbs of torque
Thank you
Is it ft/lb or is it really lb/ft if so, why?
I was corrected to calling it lb/ft
homeystar77 your right. Technically torque is measured in pound-feet, foot-pound is a measurement of work. However the mistake has been made so often that it is widely accepted to just call torque measurements foot-pounds.
Thanks!
thanks for the well explain vid
also could you tell me about using the anti-seize compound on the thread?
what is it gonna change ?
+tech270154
Using Anti-seize on a fastener is similar to using any type of lubricant. Using a lube on a bolt dramatically increases the clamping load, so it should never be used unless specified by the manufacturer.
Fut paunds?
Bravo!
You remind me or Marty from Blue lightening Photoshop. Just and amazing teavher.
simple but effective

What you torquing about
You don't meassure WEIGHT in Newton. You meassure FORCE.
Weight is a directional force that depends on your location (even on earth).
Weight would not have any meaning for torque.
Is this the main character from Bioshock?
1 foot pound is supposed to be 1.4 Nm
Nice that he blocks the chart. Waste of Time.
1 ft-lb is equivalent to
Double pipe torque wrench

Painful. All that ploppling and the dude never gets to dry vs lubed torque.

this guy sounds like Bryan Cranston! XD
torque not accurate, tension is best
CAREFULL WIT MY EYE WIT THAT SHIT...
Pound-feet. Foot- pounds aren't a unit of torque.
WAT THE FUCK!!!
Huh ? its all chinese to me
annoying hands
