My 25 year old or so Craftsman Microtork inlb torque wrench isn't really cutting it for motorcycle work. Too chunky, too long, and not suitable for the low torque (3 Nm) aluminum case bolts on my S1000RR. In true GJ fashion, this predicament clearly justifies purchasing a new tool.

After researching some options, it became clear what to do when Zoro sent me a 20% off coupon on top of what was already a fair price for Proto's little 1/4 drive torque wrench, number J6060B. Here it is on Proto's website for those interested:
https://www.protoindustrial.com/pro...meter-torque-wrench-quick-release-head-design

Proto says 9.5" long, but it's actually about 10.75" long (270mm). Pic for comparison:

The head measures 20mm across, and 10.33mm thick, 72 tooth ratchet.

It came with a calibration certificate, performed just last month, with four measures taken at three different torque settings. Every measure was less than 2% off target. It didn't come with a case, though. Just a hard plastic tube with foam inserts for shipping.

The finish is more of a satin chrome, and it looks good. Markings are inlb on the front and Nm on the back. They're not difficult to read, about the same as my 1/2" CDI torque wrench, but not nearly as clear and easy to identify as the white-on-black etching on my Gearwrench:

While the rest of Proto's mechanical torque wrenches are made by CDI in the USA, this little guy is made in Italy, and it's a beauty. The knurling is absolutely awesome, the break action is clear when the torque setting is reached, and it just feels good to hold and use. I wasn't sure if I would even keep this torque wrench because it only goes to 50 inlb, but after using it a bit I have no interest in returning it.

This is the second time I've had to work on the clutch on this bike, so I replaced the single use Al bolts with some Ti hardware. Nice to finally have a quality torque wrench for the work. This really is a great torque wrench for low-torque work, and I imagine it's perfect for bicycle mechanics as well.

What's the setup? Extension to bit holder to hex bit? Need more pics...

Awesome looking torque wrench.

Looks similar to the Facom R.306U, just without the interchangeable inserts. The knurling is way better than my Snap-on.
Sure does look similar. Love that style of round head on it. May not be the most practical but looks neat.

Happy to oblige (y)

Here's a pic with my two most common 1/4 extensions, a 3" Proto and 150mm Koken wobble, along with a TRO Ti hex bit holder and the two most commonly used bits, a T25 and a Wera hex-plus 5mm:

I've got other extensions, and bit holders, but these are my most commonly used for 1/4". I'm currently keeping an eye out for some stubby 1/4" torx sockets with six-sided flats that I can use with a ratcheting wrench for low-clearance situations.

Makes sense if they both use the same manufacturer, as both are SBD brands. No hint of manufacturer on the packaging or calibration cert, only that it's made in Italy. I suspect there's likely a USAG equivalent as well.

The knurling is amazing. Close-up shot with a Koken 1/4 extension for some comparison. It feels really good.

That knurling looks perfect. Just the peak of the diamonds knocked off, still sharp enough. Def on the list for my next torque wrench.

That bit holder looks pretty crazy!
