First time posting. My question is thread gaging. I have been told that the proper way to use a thread gage when possible is to hold the gage in you hand and thread the part down onto the gage. If this is correct, Why is this?

..I've used gauges for many years and I never heard that. The general rule I use is to hold the lighter easier to handle one. If it is a big gauge and a small part, mount the gauge and handle the parts. If it is a large part and a small gauge hold the gauge ... you get the drift. Just use simple logic. The main thing is to never force a thread gauge. If it won't go, the part is wrong, don't try to fix the part with the gauge. That is what taps, dies and machines are for. If you are checking a large number of threaded parts, you need two gauges. Compare them on a part to see that they agree, then mark one as the control. Mark the other one as your test gauge. Use the test gauge for quality control of the parts. After a checking large number of parts, check one also with the one you marked control. If the control does not fit as far on the part as the test gauge, this means you should buy another gauge and compare the fit with the control gauge. Then if they agree, your new gauge becomes your new control and your old control becomes your new test gauge. You then destroy the old test gauge. The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.
