Metric Class Z Plug Gauges
These metric Class Z plug gauges are used for precision go/no-go measuring of hole sizes and depths, checking hole location and distance, and setting micrometers. They’re also known as pin gauges. All come with a certificate of accuracy traceable to NIST that states they've passed a test for accuracy.
If a go gauge can enter the hole and a no-go gauge is unable to enter, the hole is within tolerance.
Go gauges check the minimum hole diameter.
No-go gauges check the maximum hole diameter.
