## Description

NEIKO 20743A 3/4'-Inch Torque Adapter, 150-750 ft-lb, Torque Wrench Converter/Adapter, Alerts Torque Setting, Calibrate Digital and Analog Torque Wrenches

## Features

- TORQUE WRENCH CONVERSION: This digital torque adapter converts any ratchet wrench into a precision torque wrench with a digital gauge and serves as an accurate calibration device for existing digital and analog torque wrenches.
- METRIC/SAE & BI-DIRECTIONAL: This digital adapter can calculate torque at both metric and SAE units (Ft.-Lb., N-m and kg-m) and bolsters a 3/4-inch drive with socket drive and can measure in both directions, clockwise and counter-clockwise.
- PEAK AND TRACE MODE: This torque adapter unit provides two types of modes: a peak mode that indicates when a specific level of torque is reached and a trace mode that actively shows how much torque is being applied on the display.
- NOISE ALERT AT TORQUE SETTING: The audible confirmation is accompanied by a 3 LED light indicator system to give you a progressive audio notification when reaching specified torque ratings/settings and auto shuts off after 80 seconds of idle time.
- ADAPTER SPECIFICATIONS: Torque range: 150-750 Ft-Lb or 200-1000 N-m; Accuracy: +-2%; Memory: 50; Uses 2 AA batteries.

## Questions & Answers

**Q: do the battery drain problems still persist on the 1/2" model as mentioned in several reviews?**
A: Well I have the big boy 3/4 drive torque adapter I don’t know anything about a battery drain problem all I can  say is when you get finished using it take the batteries out

**Q: Can you "preset" your desired torque and the unit beep when you get there or must you constantly watch the meter?**
A: Yes you can preset this device to the torque setting you want. This tool has 3 LED indicators and progressive audio notifications when reaching the specified torque.

**Q: Can you use it for left handed axle nuts?**
A: Yes it can do left and right turns 🙃

**Q: Can i set the torque lower than 15 ft lb?**
A: If the lower limit is 15 ft lbs, then that is the lower limit! Also, Torque Wrenches are inaccurate at their extremities.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by A***P on August 29, 2025*

Great value. Works better than my click type wrench when lower than 30 ft-lbs.

### ⭐⭐⭐⭐⭐ Impressed
*by A***E on September 20, 2020*

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.

### ⭐⭐⭐⭐ Nice, nice. Where's my headlamp?
*by S***Y on August 12, 2016*

Pros:Easy to use and works well.Save $$$ vs buying multiple wrenches.Comes with battery and a nice case.Cons:Small display that is not back-lit and is sometimes hard to read. Especially if you're working in low light conditions. I didn't think this would be a problem but it was.Sometimes it turns off before you can get the wrench to what you're working on (18 second shutoff I believe).Buttons are raised which can sometimes lead to changing your settings if you bump it against something during positioning or turning your wrench.With practice and a good headlamp, these are very minor issues and overall this is a very nice product for the price. If you torque often, you may want something back-lit.
