Prestacycle Pro TorqKeys 4Nm T-Handle Torque Limiting Tool – Torque Wrench Bit with Ergonomic Low-Profile Grip, Magnetic 1/4" Hex Bit Retention, Durable Zinc Shaft

PROS:->Accuracy at 2.4%. – (Tested with a HIOS HP100 Digital Torque meter)->Unmistakable feedback once torque is reached - (You're not going to miss it!)->Torque value of different units stamped on top of handle. – (Nm, Kg-cm, in-lbs., oz-ft.)->Can be used counterclockwise [Not torque limiting] – (Unscrew a fastener)->Magnetic tip – (Holds bits in place)->Never needs recalibration->Value – (Good quality tool at budget friendly price)CONS:->None that I can think of.WHY I BOUGHT IT:For bike specific application such as tightening handlebar clamps, seat post, saddle bolts and all other components that generally require 5Nm. It is compact, transportable and convenient than Beam or Click type torque wrenches. Though not torque limiting at counterclockwise, but this tool can also be used to unscrew fasteners. I wouldn’t use it to unscrew a thread-locker treated fasteners.BUILT QUALITY:The tool does not have any information on country of manufacture but it’s safe to say it is not made in USA. Otherwise, it would've been stamped on it. Built quality and material used seem to be decent. The tool does not feel flimsy or something that will break within the first use.ACCURACY:Very accurate! The average torque value taken from five readings with a calibrated HIOS HP100 digital torque meter was 5.12Nm. This translates to an error of 2.4%, which is well within the 10% specification.LIFE SPAN:According to the manufacturer’s website this tool is rated to have a torque accuracy life-cycle of up to 5000 clicks. The specs also mentioned that “If the logo is worn, the tool is past life”. Personally, I’d opt for the “worn logo” way of identifying the product’s end of life. Somehow, I don’t think I can keep track of when I hit 5000 clicks.DO I RECOMMEND THIS PRESTACYCLE 5NM TORQUE KEY?Yes, absolutely! It is compact, transportable, accurate and perfect for bike fasteners that generally require 5Nm of torque.

Excellent, durable and accurate tool. I bought the common torque for most things bike: 6Nm and now I never worry about torque being wrong. Definitely worth the price. Very well designed

They do well and I am satisfied with their results I have the 8, 10, and 12 sizes . I would say yes to buying them I knew to setting togue and I had no problem learning . I have watched YouTube and it has helped to be able to try out new bars on my bike even change to different stems and even replacing older style stem mounts . It works for me and I’m 68 years old and it came easy to me so I could not be happier about these tools. Go for it get them .

Great product

Great tool but I wish it was a little cheaper

Most of my cockpit components and a few other spots require the same torque setting, so this thing saves pulling out the adjustable torque wrench so often, and it seems to be quite accurate and sturdy. A good time saver and it reduces the urge to guestimate torque on delicate fasteners in haste.

Well made, exactly as described. Fast shipping.

Very practical tool and better than the torx tool that I used to use to attach my foil
