Pin gauge.
if it is marked 1.000-, what the exact diameter it is?
no class is etched on it.
as I read, (-) means no-go. so it would be smaller than 1.000000". but by how much?
thanks.

To the Toolmaker, your nice little cartoon drawing of your glass looks cool, but your solid model sucks. Do you want me to fix it, or are you going to take all week to get it back to me so I can get some work done?
RE: HELP, HELP, HELP !
no additional marking except 1.000-.
chatted with Meyer, they are shop grade, no class.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

I don't know if that was directed at me but if it was, my post was not an assumption. I know what the - after the dimension means...100% sure.

I have a new micrometer standard that calibrated at 0.0041 over the factory-etched size. I keep it in my toolchest (tagged, of course) as a reminder never to assume anything.

Where did I ask this?
All of this is outside the scope of what was being asked. He just asked what the minus meant. I told him what it meant. I also told him what the diameter SHOULD be. If it doesn't actually measure that then that's another question.
