Plug Gauges with Handle
Take go and no-go measurements with the same tool. These gauges have a go gauge on one end, a no-go gauge on the other end, and a handle with bushings. They are used for precision go/no-go measuring of hole sizes and depths, checking hole location and distance, and setting micrometers. All come with a certificate of accuracy traceable to NIST.
Check the minimum hole diameter with the go gauge end, and check the maximum hole diameter with the no-go gauge end. If the go gauge enters the hole and the no-go gauge is unable to enter, the hole is within tolerance.
