When inspecting threaded shafts and holes, thread gages are a highly common application tool. But, should you use ring gages or plug gages?

It’s not particularly common, but it is important.
But what about checking non-threaded parts? Here, smooth ring gages can be put to good use. What other kinds of gages can be used?
