Review: Very good - It looks very well made nice and simple to use
Review: It works but will not fit into every nook and cranny! - This review is written from Lagos, Nigeria for the ARM602-4 with 1/2" drive. I ordered this product when it was time to replace the cracked cylinder head gasket on my '09 Toyota Corolla with the 2ZR-FE engine. The product arrived in excellent condition and included the two batteries needed to operate it. The seller had earlier sent me instructions by e-mail on how to use it. It also includes an owner's manual with clear instructions. My impressions: it is easy to use. It is easy to learn how to use. It doesn't take you more than a few minutes to begin implementing what's written in the owner's manual (You, of course, do read manuals). Once you install the batteries you are ready to pop your square drive in and torque all sorts of things. There is a digital readout that's clear and easy to read in daylight; there is no backlight for dark places. The buzz that informs you about your target torque is loud and clear for probably most situations you'll find yourself. When you approach 90% of your set torque setting the beep begins and remains until you reach your preset torque in which case the urgent beep becomes a long buzz. You'll want to play with this tool when you first use it to get a feel for how far above torque you get it. There's a 'Peak' mode as well as 'Trace' mode - Peak mode saves a reading of the highest torque you've applied; I liked clearing this each time to see a new peak reading at the next attempt. With a few attempts I learnt how to slow down rotation to bring me as close to matching preset torque as possible, give or take. The Trace mode allows you see the torque reading in real time if that's what you want. You'll have to adjust the device to account for rotation so you can still see the screen while turning a bolt. Now, here is the catch: from my photo you can gauge the size of this tool - it will be impossible to use it in a few (or many situations) depending on the space in your engine. It was easy to employ for cylinder head bolts, camshaft bearing cap bolts, my right-hand engine mounts, intake manifold and then some bolts on the timing chain cover. The problem is that it was too large to allow me torque some bolts on the timing cover, exhaust manifold and alternator. I used it on most but the aforementioned few I had to torque by "feel". Also, this tool is calibrated for 20N.m - 200N.m (14.8 - 147.5 lb-ft). I found that all those 10mm bolts that required much smaller torques I just tightened by feel - the device won't register a readout until you reach 20 N.m, even when in trace mode. Another reviewer suggested to use this as a calibration tool for your other torque wrench instead and save yourself any headache. I do agree that another torque wrench may be needed to complement this. Over all, I am satisfied. This was all I used for the head gasket job for my car and I am pleased.

## Questions & Answers

**Q: "item torque 147 foot pounds": so what is this in standard nm please? why does it not show in the description?**
A: My advice would be by a decent “normal” torque wrench ... pay a bit more buy a Wera click... I got one of these it was unreliable in the uk as the temperature dropped it became inaccurate, I ended up borrowing a friend’s... which made me think why have digital if you have to check it with a manual one... just buy a good manual one to start with.

### ⭐⭐⭐⭐⭐ They are AMAZING!!! No need to buy again.
*by R***S on 10 April 2025*

These were exactly what I was looking for. They work great with my ratchets of pry bar. I’ve used them for torque the bolts on flywheels, oil pans, and full motor rebuilds. I would highly recommend.
