Do they sell a gauge to measure Coaxial Power Connectors?

I think youall are mixing coax power connectors that are used on many wall cubes to power the electronic devices and the coax connectors like used on the antenna cable called coax, such as RG-8, RG-6.

The mating areas of the coax power connector are not crimped or any other thing to change the mating dementions.

You're thinking of RF coaxial connectors. Aside from the fact the don't change at the mating side of the connector.

Almost coaxial power connectors have solder terminals on the wire side and they don't change shape either at the connection/interface side.

The center terminal may drift in position if you overheat the connect during assembly/soldering.

Oh. I guess we learn something new every day?

One more idea. Buy or make a tapered hole gauge: It would need to be made for the purpose to prevent bottoming out on the connector. I have a few that I made for go/no-go inspection gauges by grinding a steel rule blank and etching marks with ferric chloride.

Are you sure that your Mitutoyo calipers are not a counterfeit? I gambled and bought a Mitutoyo Digimatic 500-196-20 for $35. It was a fake. After cleaning out the shavings from the guts, removing the burrs, and squaring the jaws so that they were parallel, I did something that blew up the electronics. Sorry, no photos.

Well, I bought them some years back from an actual Mitu distributor, so I'm pretty sure they're real. No swarf, no detectable parallellism error, no noticeable offset between depth gauge and ID/OD blades, good battery life, nice case.

My cheap 'n' cheerful Chinese ones are actually quite OK as well.
