Video Transcript for Performance Tool Digital Torque Adapter Review

Randy: Hey guys. Randy here at Today we're going to be taking a look at the performance tool torque adapter. This is going to allow us to use any half-inch wrench, and then give us proper torquing specifications as we torque down those bolts for either a half-inch, three-eighths drive or quarter-inch drive.Now this offers us several different settings. We've got the standard setting foot pound, and inch pound, we have Newton meters, but we've also got kilogram per square centimeter and per square meter. So regardless of what the torque spec you're given is, you'll be able to use this to get your bolts properly torqued down.

Now it's very important to get things torqued down properly. You don't want to over tighten them, you don't want to under tighten them. We do hitch installs and inaudible 00:00:50 and U-bolts and trailer couplers and jacks, and all things of that nature. They all use different size hardware and by properly torquing them down, you're going to ensure that that bolt is going to hold.If we over tighten a bolt, we tend to stretch it a little bit. That causes it to be weak.

If we don't have it tightened up enough, then we're not getting enough holding for us on there so we know it's going to be held properly. So I think this is an excellent idea. It's a very easy to use system. The screen will rotate for you, so regardless of whether you've got it in a downward position trying to tighten it or it a little bit higher, you'll still be able to see the readout. Now you'll see when we use it here in a few minutes, it gives us different beeps.

So once we get up to 70% torque, it's going to beep. We get up to 90% torque, it's going to beep a little bit quicker, and then when we get to a hundred it goes to a solid. So it gives us an idea as we're tightening it down, how close we are and how much further we have to go.If we look right here, we're going to have 10 different presets we can choose from. This one says set zero. We don't have anything programmed there.

Readings, you set one. We've got that to 86 foot pounds. To adjust and change that, basically we want to get to it and then we hit the arrow button. That arrow button switches, so just kind of like a watch. Every time you hit it, it's going to switch over to the next number and we can go up to 150 pounds. But once we get to the number we want to change, we just hit the plus button. See that right on top. That's going to change that number. It just runs right up one through zero and then back up. So we'll just leave that at 86 that's what we're going to use and then we can hit the T that's going to lock that in for us.At that point we're ready to go. Now let's say we needed to set a different one. We'll hit our plus button again. Just go to set four here. Now it goes to kilogram per square centimeter. So we want to get that adjusted to whatever unit we're going to be using. Kilogram per square meter, inch pounds. Once we get there, we can dial it up. So let's say we want to do 26 inch pounds, just use that same strategy once we've got it where we go, we hit the T. The U here is going to switch your units and then the M button, that's our mode button. So we'll hold that down a couple seconds, turns it off, press it to turn it back on. And when we see that CAD, that's the auto calibration, so it auto zeros every time. Right here, you can see the percentage that larger O changes and that's going to give us a 10, 20, 30, 40, 50, 60, 70, 80, 90% up to 100% torque value, so we know how close we're getting there.Overall, it's a nice compact system, comes in a nice heavy duty carrying case here so we can easily throw this in the toolbox of our truck, anything like that, and always have a torque wrench on hand. And with the adapters that we talked about, you'll be able to use any size socket to get up to the torque specifications you need, going anywhere from the inch pounds all the way up to the foot pounds. It's going to have a range of 30 foot pounds, up to 150 foot pounds, so it's going to work out for any hardware, really up to about a half-inch or a five- eight size bolt. Anything larger than that, generally we're torquing it over that hundred and 50 foot pounds, so keep that in mind, but overall I think this would be an excellent thing. Throw it in your toolbox, have it on hand all the time, throw it in your toolbox at home. That way anytime you need to torque something down, you can do it properly and you won't have to worry about it.When you're ready to use it, essentially you're just going to put it onto a half inch. I like to use a breaker bar. That way you don't have to deal with the ratcheting mechanism. You can do what you want though and you'll add the socket that you need. Now remember you do have the adapters, but go with the largest one that you have. If you try to do a hundred foot pounds of torque with that quarter-inch adapter, you're likely to break it. If you're going to do that kind of weight, use that half inch.And then we're just going to hit the M or mode button that's going to turn it on for us. It goes through that normal CAD screen, which is going to auto calibrate it and then we'll hit that plus button just so we can make sure. Yeah, I'm going to torque these down to 86 foot pounds. So you've got that, that we set earlier. We'll hit our T, that says that's the one we want to use, and then we'll start torquing it down and here you can kind of see where that screen comes in pretty handy, that rotational aspect. Then we can rotate it so we can see it.(silence) Just like that. Of course, tires on these are crossing pattern. Overall guys, I find this thing really handy. I think it works out well. That small compact storage case to keep it with you all the time. You have a blowout, you can get proper torque on your wheels here. I also liked that it's adaptable with all the different settings that we have, inch pounds, foot pounds, Newton meters, and the metrics. I think it just is very handy. I think you'll find it very useful and anytime we can properly torque something down, we know it's going to be safer. So I definitely like it and it's definitely something I would own.

Digital Torque Adapter - PTM206

Average Customer Rating:  4.9 out of 5 stars   (10 Customer Reviews)


Maybe I am just "dense" or something but the manual is not informative enough to explain how to use all the buttons. So it took me quite awhile to "trial and error" until I figured it out. Once I got it, it has worked good. I torqued all my trailer lugs and checked my truck lugs without a problem. It would just help a lot if the manual was written better.


A simple way to make any 1/2" socket wrench into a torque wrench. Instructions were easy to follow and the product worked just as advertised.


Turned my standard 1/2" breaker bar into a torque wrench. Just used it on a project and it worked perfectly. The beeper system is a great feature and the multi-set option let me step up the torque with out resetting each tightening cycle.

Still working great.

I ordered the digital torque adapter. When I ordered I needed the part immediately, so I was happy when it was in my mailbox the next morning. I haven't used the part to much yet but from the little I have I can say it will make my shop much more efficient. I am very satisfied with the part and the customer service.


Have not had a chance to use it yet. It appears to be a quality tool. I’m sure it will perform as advertised as all my purchases from etrailer have.


Your team was amazing at ensuring order accuracy, even after some last minute changes. Thanks for the last minute adjustment and the quick delivery!


Appears to be quality. I hope it works well.


awesome tool
