Review: Very useful! Feels like quality - I bought this based on all the existing recommendations. The Torque Test Channel sort-of-reviewed a competing digital torque gauge product from a no-name brand and said it was good; this ACDelco version was only a little more expensive and labeled with a recognized brand. I have confidence in the torque readings and they match my click-type torque wrench pretty closely. The unit itself feels pretty durable. Uses lithium coin-cell batteries, which is smart for cold-weather function. Can't speak to battery life as I just bought it.
Review: Tight... - These torque adaptors work great and are accurate. I have one in two different toolboxes.

## Features

- Transform your standard ratchet wrench into a highly accurate digital torque tool. It delivers professional-grade accuracy of ±2% clockwise and ±3% counter-clockwise from 20% to 100% of full scale. You can easily switch between four different measuring units to suit your specific needs: N-m, kg-cm, ft-lb, and in-lb.
- The adapter features two versatile measuring modes. Choose "Trace Mode" to view real-time torque readings as you apply force, or select "Peak Mode" which holds and displays the highest torque reading measured until you manually press the power button to clear it to zero.
- Equipped with an intelligent audio alert system to ensure precise tightening. An intermittent buzzer will start sounding to warn you when you reach 90% of your preset target torque value. Once the target torque value is reached, a high-frequency buzzer will sound to alert you not to pull further.
- The smart memory function automatically retains your last selected "mode" and "unit" settings, even after you replace the coin cell batteries. Additionally, it features a unique counter function that records the number of times the adapter has successfully reached the target torque (displays up to 999K times), allowing you to easily track the tool's usage history.
- Designed for durability and efficiency, the LCD display will show "999" and a high-frequency buzzer will sound if the applied torque exceeds 120% of the maximum torque, protecting the tool from damage. Powered by two CR2032 coin cells, the device includes an Auto Power Off feature that shuts down automatically after 60 seconds of no use to preserve battery life. It is available in 3/8” (ARM602-3) or 1/2” (ARM602-4, ARM602-4A) square drives.

## Questions & Answers

**Q: I see reviewers make reference to audible warning. Does that mean it provdes an increasing tempo of beeps as you approach the torque you've set?**
A: The beep will increase temp as it reaches the target torque limit.  Once it is reached, it will provide a constant beep sound to notify it has reached.

**Q: Can I use it as a torque wrench?**
A: Yes. As long as you have the room for it.  A little clumsy for torque over 100 ft. lbs.

**Q: The manual says the power button should not be pressed with torque applied. I accidentally did that. Will it cause accuracy problem?**
A: I am pretty sure that the device on start up takes a reading from the strain gauge in the device and whatever that reading is defines that value as zero torque applied. Same thing with digital scales in the kitchen, on startup they determine what zero mass/weight is. Whatever reading/torqued applied will be wrong, if a load was applied on startup.Once off power the device on with no load and I believe you will be in business again.

**Q: I don't see in specs the accuracy percentage?**
A: Here is the ACDelco page for this Torque adapter: http://www.acdelco-tools.com/index.php?route=product/product&product_id=132It says "Accuracy	CW ± 2%; CCW ± 3%".

### ⭐⭐⭐⭐ Good product. Easy to set.
*by M***K on September 24, 2025*

This is a good product. It is very easy to use compared to the Chineese designed variants on Amazon. Those are near impossible to quickly set. This one is pure simplicity with no memory functions, because you just don't need it its so quick to adjust. Comes with a certification and useful instruction manual. I just returned a half price competitor - it actually performed the same, but it was frustrating to use and wasted 15 minutes every time you needed to switch the settings. This one also works in the CW and CCW directions without having to adjust anything.
