Video Transcript for Powerbuilt Digital Torque Adapter Review

What's up everybody, it's AJ with Today, we're gonna be checking out these Powerbuilt Torque Adapters, and now they're going to be a 3/8 version and a 1/2 inch version. And what happens is you put this adapter on your ratchet and it makes it a torque wrench. That way you have the rating for your foot-pounds right here, it's got a read out here so whether you're replacing a spare tire or putting a hitch on, you can see a reading about where you are. The difference between these are the 3/8 one is going to have a torque rating from 19.9 all the way up to 99.6 foot-pounds. Now the 1/2 inch one is going to have a torque rating of 29.5 all the way up to 147.6 foot-pounds.

Taking a closer look at it, the adapter, this is going to be the power button here, so that turns it on and off. Now it does have an automatic shut off after 80 seconds, so if you're not using it and you set it down and forget about it, it shuts off, that way it doesn't waste the battery. Now there's a few different settings you can do. There's the plus and minus at the bottom, that's where you can adjust the torque rating wherever you want to put it, or wherever the instructions tell you to put it. You can adjust it there, that way it'll let you know when you get close to there.

They got peak and trace up here, that's the modes for this adapter. So peak is going to let you know when you hit that number that you set there, so if you're reaching in and you can't really see it it'll sound the beep, and then when I, let's say I was going in here in the wheel well, and I pulled it back out, it would still be flashing that number so I'd know what I just hit and was like, "Oh, okay, I got it." Now, if we went for trace mode, it's just going to read it in real time so if I was torquing this right here, I'd have it on, that'd be going and it'll tell me in real time as I'm torquing it what the number's going to be. So that's if you can get eyes on it, it's probably better for that mode. Now I've already showed you how you can adjust that up and down with the plus and minus, just going over that one more time. And then wherever you want to put it, you can hit the memory button and it stores up to 50 of the last torques you used, so that's letting us know that that's what was the last one we did.

And then to change the measurement, so we're on foot-pounds right now, you could hit memory and trace, and you see the arrow is going to move along the top to show you all these different measurements up there. Another thing I wanted to point out when you're adjusting the torque setting, you could go one at a time, that's going to take a little bit, but you can hold down, it'll go way quicker that way to get to where you want. We want to be 85, so just back it up now, and now it's set. Now we're getting ready to torque down the lug nut, got it set for 85 pounds. There's gonna be two beeps.

There's one beep when we're within 20% of our foot-pounds we set, and then the second one is gonna be a higher pitch beep letting us know it's torqued fully. So let's go ahead and put it to the test. There we go. Comparing it to the torque wrenches we use around here for hitches and stuff in the base, this one's going to be a little bit off, it's not as accurate as this, but I think this is still going to be a good thing to have just in case of emergency. So if you do have to replace a tire, let's say you have a blowout, you're putting the spare on, you want to make sure that it's torqued down so you can get to the shop to get it fixed. So it wouldn't hurt to have this to at least be able to do that and know you're in range somewhere of it's tight enough I have the confidence I can go on the highway or I can get on the road. Another nice thing about it is it comes with the carrying case, that way it's just not lose in your toolbox or in the back of your vehicle. It seems nice and heavy duty. We also have this tool here, you can put this on the end, just like that, and then you'd put that in a vice and you could attach another torque bar to it, to see if the readings match up or not, you can use it to help calibrate an existing torque bar. Definitely going to be one of those good things to have sitting around because a lot of things we do around here, they have in the instructions specific torque settings. And if you don't have one of these, you have no idea if you're even close to that, so I'd rather have one of these around. So I can use it on my trailer, a hitch, or even replacing a tire, this is going to come in handy. Well, thanks for hanging out, and I hope this helped..

Average Customer Rating:  4.5 out of 5 stars   (2 Customer Reviews)


The product was what I wanted. A way to check out my torque wrenches. There could be a few improvements made on the product to improve it. That is for the manufacturer todo. For the price it is great for checking torques. Would do it again.. Thanks.


Product works well it does what is advertised thank you.

  • How To Set Or Erase Torque Settings in the Memory of PowerBuilt Digital Torque Adapter
    The PowerBuilt #ALL940962 Torque Adapter does not have a clear memory function. As each new value is saved to memory it is recorded into a bank of 50 locations. When a new setting is saved to memory it goes into location 1. When a new value is saved it goes into location 1 and the value previously in one is bumped to location 2. This continues to happen until all 50 locations are filled, then as a new value is added, the 50th value is lost. I have attached a link to this product and to...

  • Installing a Trailer Hitch Receiver to Proper Manufacturer Torque Specifications
    There really isn't a way to torque your bolts to specs without using a torque wrench. Not using this will void your warranty because it wasn't installed properly. I recommend getting the Powerbuilt Dual Drive Torque Wrench - 3/8" and 1/2" - 10 to 150 ft-lb # ALL944001 or the Powerbuilt Digital Torque Adapter - 1/2" Drive # ALL940962 to convert your traditional ratchet into a torque wrench.

    Yes, the Powerbuilt Digital Torque Adapter # ALL940962 will still work just fine using an adapter so you can install the 1-7/8" 12pt Socket - 3/4" Drive # ALL643216.

  • 1/2" Wheel Stud Lug Nut Torque Setting And Tightening Pattern
    The proper lug nut torque setting for the Kenda 5.30-12 Bias Trailer Tire with 12" White Wheel # AM30859 is going to be between 85-95 ft/lbs. It is important to remember to evenly torque the lug nuts in a star pattern in stages. If you try to tighten the lug nuts out of sequence or apply the full torque rating before you tighten any other lug nuts the wheel will more than likely be uneven on the hub face causing vibration issues. Follow the torque sequence in the picture but do them...

  • Recommended Torque Wrench for Trailer Hitch Installation
    For the Curt Trailer Hitch Receiver - Custom Fit - Class II - 1-1/4" # C12172, there really isn't a solution other than to use a torque wrench. Without torqing the necessary bolts to the manufacturer specs, you void the warranty and can have safety issues when using the hitch receiver. If you want to purchase one, I recommend the torque wrench # ALL944001 or the digital adapter # ALL940962. There are many auto parts stores that now rent tools as well if you prefer to go that route, but...

  • Torque Specs for Axle Spindle Nut and Lug Nuts
    There is not a torque spec on the axle nut for the Dexter Trailer Idler Hub Assembly for 3,500-lb Axles - 5 on 4-1/2 # 84545BX. The axle will have a castle nut that should be tightened until there is no side to side play and then backed off to the next notch in the castle nut for the cotter pin to retain the nut. If you click on the video link I provided for replacing hubs and fast forward to the 4:45 minute mark you can see the procedure. If you have an EZ lube spindle, then the spindle...

  • Lug Nut Torque Range for 1/2-Inch Wheel Studs
    The recommended torque range for lug nuts varies by the stud diameter, wheel size and wheel material and if you refer to the linked chart you can see the torque range for 1/2-inch studs starts at 75-ft-lbs and goes as high as 120-ft-lbs. Many RVs use a 15-inch or 16-inch steel wheel and for wheels this size on 1/2-inch studs that are secured with standard 60-degree coned lug nuts the torque range is 90 to 120-ft-lbs. If you need a torque wrench we offer several wrenches like # ALL944001...

  • Lug Nut Torque for Trailer Wheels
    The Kenda 205/65-10 Bias Trailer Tire with 10" White Wheel - 4 on 4 - Load Range E # AM3H460 don't have a suggested torque value. The torque is based on lug bolt stud diameter and the lug nut type. I've attached a chart to assist. most of the 4 on 4 inch hubs will have a 1/2 inch diameter lug bolt and a coned lug nut so they would be torques between 75 and 85 foot lbs. If you don't have a torque wrench, I recommend using the Powerbuilt Digital Torque Adapter - 1/2" Drive # ALL940962....

  • Installing Trailer Hitch on 2018 Subaru Crosstrek without a Vehicle Lift
    The Curt Trailer Hitch Receiver # C13382 is the easiest install of the trailer hitch options for your 2018 Subaru Crosstrek. If you are okay with working in extremely close contact with the underside of your Crosstrek, you can install it while the car is on the ground. Most people will prefer to use some jack stands like # PTW41021 or the jack with stands # PTW1605 to give you a little more room especially because an extra set of hands is also helpful.
