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.

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.

Plug Gauge Sets

With Case

Take precision go/no-go measurements of hole sizes and depths, check hole location and distance, and set micrometers. These sets have 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.
