NEIKO20741A 1/2” Digital Torque Adapter, 29.5-147.5 Ft-Lb, 1/2” Drive Digital Torque Wrench Converter/Torque Wrench Adapter, Alert Signals Torque Setting, Calibrate Digital & Analog Torque Wrench

I bought this 1/2", 29.5-147.5 ft-lbs torque meter to check my cheap Harbor Freight click-type torque wrench that seemed not to match the 100 ft-lbs lug nut torques applied by my dealer. It has proven that my torque wrench was reading low!The instructions are just OK. They are typical of a non-English-speaking company, but better than many. There are no contact details for the company. So, you're on you own after purchase.In simple terms, you turn the device on and set the desired units, which in my case were ft-lbs, as indicated by a small arrow pointing to F-Lbs on the display. Then you choose either Trace or Peak Mode. Peak mode displays the torque being applied and keeps the display showing the maximum torque applied when you stop. You can then put this into memory if you want. It was useful to see when my torque wrench clicked. In Trace mode, the device shows the torque being applied at any moment, but a beep will sound as you approach a preset torque value then a continuous tone once that torque has been achieved. A red LED illuminates in sequence with the beeps and tone. The display reduces and returns to zero when the torque is reduced or removed, unlike in the Peak mode. You pre-set the desired torque for the tone by pressing the + button. The display will show an incrementing reading of torque that will increase faster if you hold the button in for a short time. I found I often overshot the desired torque and had to use the - button, pressing it several times to reduce the torque setting to the desired amount.After a few seconds, the flashing torque setting returns to 0.0, which is the torque being applied (in this free state, nothing). Then, you insert the meter into the socket and wrench and start to tighten the fastener in question. I found you have to be careful not to accidentally press any buttons when you insert the meter. Check the display before you start to use it. It should read 0.0. Once a preset torque is entered, it remains in the meter for next time. Turning it off and turning it back on still retains that pre-set torque. So if you need another torque setting at another time, you will need to adjust the value as needed. The meter shuts itself off after a time to conserve battery power.As you apply torque, the display will show an increasing torque value and as it approaches the pre-set torque, the unit starts beeping and when you reach that torque, it changes to a continuous tone, just like the click of a torque wrench. I had no issues with hearing the beeps and tone and I have "old" ears!I found that the solid tone sounded well before my torque wrench clicked; 30 ft-lbs too early at a setting of 100 ft-lbs on the wrench and 100 ft-lbs on the meter. But which one was correct? - the meter or the torque wrench? Fortunately, I have a simple beam-type torque wrench that is always accurate. When I used that with the meter, the indicator pointed to 100 ft-lbs at exactly the time the solid tone came on. That showed the meter was accurate and that my torque wrench was bad. I re-calibrated the torque wrench and now it clicks at the tone! - AWESOME.I have had no issue with the batteries so far after two days. They are two AAA's, not CR2032's as I was expecting after reading some reviews. The beeps and solid tone are easily heard in quiet locations. The unit is very accurate. The display is small, but I wear glasses and can see it with no problems. Only time will tell how durable this meter is and I will update if anything happens.For $40, this is a great device to get accurate torques or to check and re-calibrate your click-type torque wrenches.It comes in a very sturdy case for storage, which is perfect for a precision instrument. It's also much cheaper than a quality digital torque wrench, which could be 3, 4 or 5 times the cost, at least. It will add about 2 inches of length to the wrench and socket setup. So, tight spaces around the fastener might not be accessible. It is ideal though that any length wrench can be used to apply torque and know what that torque is. This meter measures actual torque at the fastener, independent of wrench length. There are often spaces where a full size torque wrench just doesn't fit, like in a wheel well when repairing brakes.This torque meter has already paid for itself for me! I wish I'd bought one earlier.

The specified torque for the E60 BMW, rear axle nut is 310 lb-ft, or 420 Nm. It's not practical to have a separate torque wrench that reaches up in to this torque range, and so the NEIKO 20743A 3/4”-Inch Digital Torque Adapter provides the perfect solution for that once-in-a-while, high-toque application.To obtain accurate torque readings, the head of your breaker bar (4-foot NEIKO pictured) needs to be supported at the same elevation as the axle nut. The torque adaptor needs to be clear of any such support. A drift-punch is inserted into the ventilated brake disc and rests against the caliper mounting bracket, to provide anti-rotation under the great load. A scissor-jack and blocking are used to easily adjust the support up to the proper elevation. Make you setup so that you are pushing "down" on the breaker bar (and don't tear a bicep). Apply the downward force smoothly and progressively.The torque adapter provides audible feedback of when you're approaching your target value.Overall an absolutely wonderful tool, and takes only a fraction of the space that a full torque wrench in this rating (420 Nm) would take up in your tool box.One of my best purchases in the last 10-years.

I bought this to go with a Matco 3/4" extendable ratchet to have a 3/4 torque wrench without having a single use tool. So far it has preformed as expected.The only negative that I have for it, up to this point, is that the audible tone is very quiet. Can't really hear it in a medium noisy heavy equipment shop.

I use this to check calibration of my torque wrench. However, if you dont own a torque wrench this will allow you to use a normal ratchet or breaker bar to properly torque something. It has visual and audio indicators as well. This let's you program the torque you want to apply and it will indicate when it is getting close and when you have achieved the desired torque. Very useful.

works perfect . thanks

Five stars because it works just fine. Mine doesn't use batteries up as others have said. My batteries are still going after almost 6 months of use. I have had no issues with at all. Does the job.

LCD screen leaked after about a year in the garage- now I can’t see the units setting

I bought this in 1/2 drive and it was delivered today. Me being me I couldn't wait to try it out. I have a 1/2 " drive torque wrench that is more in the middle of the scale as far as pricing and a 3/8" from Harbor Freight that well is what it is. Both have some years under their belt, so I wanted to calibrate them and that's why I bought this. The good one I found to be about 4lbs off and the Harbor Freight one was about 9lbs off. I do like how easy it was to use, just put on end in my vice and turned it to foot pounds and it worked great. I would recommend this tool.
