jspenco: Really nice once you figure out how to set the few buttons. Feels sturdy and it’s nice to know I have the right torque from the buzzer sound.

OVillanueva: As a hobbyist mechanic who enjoys working on my own cars, I decided to invest in a heavier duty torque wrench for critical engine bolt applications. After researching options, I settled on the ACDelco ARM601-4 and have been very satisfied with its performance.

This wrench is built sturdily and has a nice weighted feel to it. The digital display is bright and easy to read. It covers a wide torque range up to 147 ft-lbs, which is plenty powerful for most automotive needs short of heavy equipment.

I've used it for torquing lug nuts, axle nuts, engine cylinder bolts, and more. The accuracy is spot on each time. The wrench beeps when you reach the set torque value so you know when to stop. This gives me confidence I'm applying the manufacturer's torque specs correctly.

The battery life is excellent, lasting for several months of weekend use between charges. The molded case it comes with is also handy for storage and protection.

For anyone working on cars in their own garage, this heavy-duty digital torque wrench is a must-have tool. The ACDelco ARM601-4 provides reliable and accurate high torque capability without breaking the bank. I'm glad I chose it over...

Andrew Atrens: Quality is a little suspect, in particular it’s difficult to power off properly. Which means you end up changing the batteries frequently. Not a timesaver when it’s unexpectedly bricked due to dead batteries.

Amazon Customer: I like the fact you can see the torque you are at. My old torque wrench sometimes seemed like it would never click. I like the digital setting. Wish the display was a little brighter. Also have to make sure the unit has not powered down before you started tightening bolt. Its shorter than my other mechanical wrench so to get say 100lbs torque it takes a good amount or effort. If you are in a difficult position (overhead bolt) it can be challenging.

MANUEL A.: De muy buena calidad, le recibí pero me toco devolverla porque me equivoque en la capacidad de torque que requería. La devolución fue exitosa y rápida.Por eso siempre prefiero a Amazon, por su responsabilidad y eficiencia con sus clientes.

Nicholas Gallan: Pretty decent tool, used it for some engine work, suspension, and a few tire changes. I enjoy the accuracy and the warning beeps letting you know exactly how close you are to spec, without having to watch screen.
My main dislike is that I feel the screen could be a little brighter, or use a backlight of potentially. Overall a nice upgrade.

Karin S.: So far this has been a great tool. I have used it multiple times now and the controls get easier each time. I really like the feature that logs the max torque, so when you are in an awkward position and you can not see the meter, you can take the wrench off and see how close you are to the actual torque requirement and stop or keep tightening. The wrench says it goes from 4 to 99 ft-lbs, and it does, but there is a catch. If you read some of the other reviews you will see that some are saying that it does not go down to the 4 ft-lbs, and I did experience this when I got it out of the case for the first time. I was pretty bummed and a little T.O'd that the lowest I could set the tool was 10 ft-lbs. It seemed like it was false advertising and was ready to send the tool back, BUT I decided to use the tool and found out that it starts reading at 4 ft-lbs, so you can torque down to 4 ft-lbs, but you just can not set the alarm that low. So I figured that on the occasion when I have a very light torque I could just watch the digital meter. Most wrenches don't go down to 4 ft-lbs so not having an alarm is not a big deal for me. The wrench overall has a sturdy construction and it has a...
