Great to get the torque right
I work with a lot of SMA connectors in microwave applications at 10 and 24 GHz, and 3.5-mm connectors at 47 GHz. The torque has always been a guess until I got this wrench. I am sure that I'd been over-tightening these connectors for many years. This wrench fits into most spaces where I am installing these connectors. It gets to places that my fingers can't, and even slim open-end wrenches can't go. It doesn't fit everywhere, but it fits into 90% of those spaces and does a consistent job.

Three Stars
Works fine. Relatively large outer bore makes it useless with closely spaced SMA connectors.

Only one wrench, not three like photo. Good wrench
The advertising page is a little misleading. I was expecting (hoping) for the 3 wrenches pictured of different lengths. I received 1 wrench. Works well and much easier than the standard type torque wrench that costs far more.

Torque Wrench, C'Bore must have
I work with a lot of different size fittings for communicaiton devices and its a known problem of overtightening can break the bulk head connection. This device is perfect for tight spaces, and gives you that little extra in reach to tighten the connector. Definitely a good buy for any person working in communications field with bulkhead connectors. Cheers!

Remember to specify the torque setting.
That is, if you want it set to 5 in-lbs. My research indicates that is what Agilent recommends for their test equipment. I forgot to do so when filling out my original order, but I was able to send a quick follow-up email in time and KCR Products made the change for me. Completely pleased.

It works fine
Just what I needed to tighten the SMA connectors to 8 lb

A worthwhile purchase
In addition to being a good, calibrated torque wrench for SMA connectors, this wrench makes it very easy to screw on SMA connectors in very tight spaces. The other available SMA torque wrenches, which cost five times as much, cannot be used in tight spaces.
