These are not bore gauges! They are hole gauges used by machinists and toolmakers. Some people refer to these as snap gauges. They are spring loaded and have a locking device on the handle. You try and tighten them when you are located on the largest part of the I.D. You then measure them with a set of outside micrometers. Not very accurate, they are not designed for precision work. That's what bore gauges are for. And I don't mean "gun bore" when I say bore gauges.
