How to use torque wrench for beginners (2023)


Click THIS LINK for the worlds EASIEST how to video on using a torque wrench for beginners!

I wanted to show people how to use a torque wrench this video will help the absolute beginners.

I needed a torque wrench for working on my sons truck, I didn't realize how expensive a nice digital torque wrench can be. I ended up like most people forking out 20 bucks on a basic inch-lb wrench and stared haplessly at the numbers on the handle with no clue how it worked.

Then spent the next 30+ minutes getting confused by the instructions and what I found on the internet. There are a ton of review type videos out there and there are as many different types of torque wrenches as there are bolts to turn.

Hey everybody, this is paul again.

I just went out and one of the things that I realized I was going to need as part of this 97 chevy s10 project was a torque wrench.

I've never used one of these tools and I could easily go ask some friends that I know have them and know how to use them, but that really defeats the purpose of this channel and what we're doing here.

So what I did was.

I went down to the auto parts store and I was hoping I was going to find me a real fancy, digital torque wrench that I could just tick up and take down, and I could set my foot pounds and then have have a field day with it.

Once I looked at those I realized they were pretty expensive and they're in the range of 100 150 dollars for a decent one, digital torque wrench- and I really you know not.

I don't have that kind of money to be thrown around at tools.

So I found this guy and this is a kind of like an off the wall.

I don't even know what brand it is to be honest with you and it's not written on any of the documentation.

The little pamphlet there's a little little pamphlet that came with it uh, it's not anywhere on there.

So here's a 20, torque wrench, okay, I went online last night.

I spent about a half an hour trying to trying to transcribe these beautiful instructions into something that would make sense to me.

I finally found one youtube video.

It was really good and he answered the one question I had so I'm hoping that with this video, I'm going to save you about 30 minutes of your day, and we can answer all your questions.

Instead of so you don't have to go online and look at a bunch of different videos to get that.

One question answered so first thing you want to do is this is a inch pound, torque wrench, so the irony is uh.

I'm looking for foot pound everything's in foot pounds in my in my maintenance guide, so um I was, I wasn't sure how many inch pounds were enough, foot-pounds, right and uh.

I felt pretty stupid when I flipped this guy over and right at the bottom here and I hope it's gonna catch but you'll see one foot-pound equals 12-inch pounds now, if you take the pound off the end of that, and you ask me paul how many answers are in a foot, I could have told you, so we want to start with the instructions.

Okay, ladies, when you you say that we never read the instructions, that's because you're asking us to build things that we're really not interested in in this case we're interested in this.

So I'm going to read the instructions and you know they get really cryptic uh.

I'm not I'm not familiar with the industry that built this tool and I'm not familiar with the industry.

I'm learning, but I'm not familiar with the industry that uses this tool.

So some of the terminology gets a little crazy.

I'm gonna, I'm just gonna kind of read through this and then I'm gonna, I'm gonna go through the example.

I'm gonna do the example and I hope that answers any questions you have about these uh non-digital, torque, wrenches and uh, and and makes to where you can actually use this thing: how to use your new torque wrench, balancing wrench in hand with graduations visible unlock the knurled handle by turning the lock nut counterclockwise.

It's a c figure one.

So I'm looking at this and I go well where's figure, one.

That's figure one right there.

So that kind of looks like the back of this guy and uh.

You know, and then I got a little hung up on a couple things like graduations and the word knurled and it's spelled with a k, so I kept calling it canarald.

I went online and I looked up in uh on the and I looked up the word knurled and all knurled is the lathing technique.

That applies this diamond pattern to the handle.

So what they're saying all they had to do is say turn handle but they say turn knurled handle and it throws me off again uh simple, simple stuff, but okay, so we have this lock oops.

I took it away.

Sorry we have this this right here, so I'm I turned it counterclockwise to loosen it up, and then you have a couple settings here.

We have this in inch pounds on this side and on the other side, we have it in newton uh, we're not from england or europe.

So we're going to stick with the inch pounds because that kind of works for me.

So I'm going to go ahead and set this to zero okay and so now we are in inch pounds and we have torqued it out to zero, so yeah and these this particular one's within four percent on accuracy according to the instructions.

So so so you can see that okay, so now what you're looking at is our graduations are set to zero.

Then there's a vertical bar here and you can see these little slide bars coming from numbers and those numbers count up in increments of 120 inches or inch pounds.

Their example says to set this to to uh 504 inch pounds.

What you got to do is you turn this oops.

I keep taking this out of focus.

Sorry we're going to turn this knurled handle uh clockwise to move it move it up, and it's going to slide up this arm here until we get to the right setting okay.

So it's going to be kind of hard for me to do this while you're watching, but I'm going to give it my best shot.

So, as you can see, as I turn this, it slides up the bar all right and we want to take it to 480 because we're going to set this to 504 so where's my 480s up there right up there right up there, so we're gonna.

Take this to 480 and you see what I'm doing is I'm stopping.

I gotta set it to zero right at the 480.


It is okay, so I'm going to let this focus again all right and you can see, there's the 480 and you can see it comes down and zero.

That slide touches the vertical bar and it's at zero.

So now we're at 480 foot pounds of torque, and if my memory is that's, I think that's 40 pounds of foot-pounds of foot-pounds of torque for 480 inch pounds of torque.

So now I need to get the 504.

So what I'm going to do is I'm going to take this? What they call the graduations and I'm going to go, I'm going to count up 2 1 2.

This is actually, I believe it's.

Basically, this is foot pounds, so two foot pounds two times 12 would be 24, so I'm sitting at 480 on my on my little chart here.

So I'm going to click this I'm going to move this over to where the two lines up with the vertical line, I'm just getting it because it gets kind of that's kind of turkey get on there, got it okay.

So now the two is on that vertical line.

Okay- and you see we're just past the 480 that 480 slide mark okay.

So now that two represents uh set this back down for a second, the two represents uh uh 24 foot, pound uh inch pounds of pressures.

So you add the 24 inch pounds to the 480 and you get 504 inch pounds of pressure.

So when they talk about setting in the instructions they they use.

The example of 504 inch pounds that translates to 42 foot-pounds of pressure being applied to the bulb.

So I hope this was informative.
