🔧 TZTOOL Precision Torque Wrench 2-20 Nm Review

I used this to fit a stem onto a carbon steerer tube - and while I probably won't really need it I'm glad I bought it - good quality - nice feel in hand, a good accessory set and relatively clear instructions - all in a cool and compact body

Wrench works great. There's nothing like applying the right torque to fragile bike parts and avoiding damage. A torque wrench takes the guesswork out. I am very satisfied with the filling of my instruments.

The tool is very easy to use. Outstanding quality for the price. I mainly use this tool on my bikes. Basically seat adjusters that have torque requirements. I liked it so much I bought it for my local bike shop as they didn't have a small universal torque wrench on hand. A little love goes a long way at LBS.

I ordered this torque wrench for work on my bike. After reading and following the grammatically incorrect instructions, the torque wrench did not work (click) on any of the settings entered! I almost twisted the screws trying to get it to work! Instead, I took my bike to a local bike shop for repairs and returned this frustrating Revain torque wrench. Spend the extra money and get a quality torque wrench instead!

To save money I ordered this instead of full price tools. error, how unusual. When accuracy matters, don't skimp. This thing was useless and didn't even come with the proper instructions. Glad I tried the old screws first before ruining something good! A barely perceptible click (even at a higher torque than set). I'm glad I can come back for a full refund but don't waste your time.

Fraudulent test results in attached specification! When I received this product I tested it with a $300 SnapOn torque wrench and the actual results were over 40Nm higher than the attached test results stated. Glad I tested it first before using and breaking the bolt on my new mountain bike. Attention buyers. For your information, test results are handwritten and not printed on original specifications and test result sheets.

It is very well designed and functional. The torque settings I tested at Oak Ridge Atomic Labs were within 0.05% of true Nm, which is exceptional for even a torque set costing ten times as much. This is a hex head but remember if you have sockets they will fit. My main concern is that if the user is left-handed, he, she, or she (trying to be politically correct!) might misinterpret the "click" sound that means the correct torque has been achieved. I would buy a replacement set in a heartbeat…

I bought this torque wrench to assemble an e-bike. I had to tighten some bolts to 4, 6, 10, 14 and "between 5 and 7" Nm. While more subtle than some might expect, the click is only slightly less than the much larger 3/8"-1/2" torque wrenches. The torque can be adjusted between 2.0 and 20.0 Nm in 0.1 Nm increments. I haven't checked for accuracy, but if I do I'll update this review. The tool comes in a box with different sizes and types of nuts/bolts. If I had to lower the overall score it would
