Despite its rapid functionality, it ensures a secure and reliable connection, making it efficient, versatile, and user-friendly.

Reversible Ratchet
A torque wrench with a reversible ratchet allows for easy rotation in both directions, making it versatile for tightening and loosening tasks. Efficient and user-friendly, it simplifies operations and is built with durability in mind.

LCD Display
A torque wrench with an LCD display features a digital screen for showing real-time torque values. This allows for precise readings in a clear and easy-to-read format, enhancing accuracy and usability. The LCD display is user-friendly and often includes features like audible alerts for achieving desired torque values.

Battery Compartment (NOT Included)
The torque wrench battery compartment is the space designed to house the batteries that power the tool. It typically includes a cover or lid that can be opened to insert or replace batteries. This compartment is an essential part of the torque wrench, as it houses the power source needed to operate the digital components of the tool, such as the LCD display and any electronic features.

Customers say
Customers find the torque wrench kit to be solid, easy to use, and appreciate its loud audible beep when at spec, with one customer noting the buzzer and LED alerts ensure accurate torque every time. Moreover, they consider it good value for money. However, the functionality receives mixed feedback, with some saying it works really well while others report it rarely works. Additionally, durability is a concern as multiple customers report the screen breaking within two years of use.

ACDelco Digital Torque Wrenches Review
These are really well made, accurate and once you read the directions and use them a few times, they are pretty easy to use. Huge Value compared to other high priced torque wrenches – they feel just like my Snap On digital ones and function just the same!

good wrenches
Iâve been using these for a couple months now. Once you get familiar with the settings, they are pretty simple and work really well.

quality and performance justifies the price
From automotive repairs to machinery maintenance, this handles high-torque application with ease. excellent build quality, feels solid and well-balanced in hand with sleek rugged design. Digital display is a must and audible alert really helps when you approach and hit the target torque. It has a wide range and accurate switching between units. If you are serious about precision and reliability, this tool is a great investment. It might not be the cheapest option but quality and performance justifies the price.

It’s a Taiwanese torque wrench set. (with an American name)
Seems to be decent quality and they both work fine. I’m surprised Amazon ships these delicate instruments, in their plastic cases, just in a cardboard box with no additional padding. I tried to fill in the warranty web-site, but it looks like a 6 year old must have put it together, I gave up. Lastly, doesn’t anyone proofread instructions for these foreign companies? These are made in Taiwan. I’m just a hobbiest, so these will be close enough for what I’m doing.

Donât buy non resistant to impact
3rd time I use it. It fell from my working bench, didnât hit anything, just hit handle first on floor and the screen broke. The screen broke from the inside the outside is fine. It wonât start. Contacted via email customer service. They responded right away. No warranty for that. Purchased in Nov 2024 what a waste of money for such delicate tool for mechanic work. I wonât recommend it at all unless you buy the 3 year warranty. And even with the warranty it is an inconvenience cause you defeat the purpose in buying on sale and the inconvenience on possibly stopping a job till you get your new tool.

Gettin older and can’t read the scale on my older chrome wrench. Very happy being able to read the digital readout. A fair price for a good tool set. Didn’t know however though AC Delco gear was made in china. O well.
