Plug Gauge Sets
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.

Target-Size Plug Gauge Sets
Get your choice of one target-size gauge with 12 larger gauges and 12 smaller gauges, graduated in 0.0001”. Also known as tenth-step gauges, they’re often used in metrology labs, quality control departments, and tool rooms for setting snap gauges and comparators. They measure hole sizes and depths, check hole locations and distance, and set micrometers. All come with a certificate of calibration 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.

Wear-Recognition Plug Gauge Sets
To indicate when you need to calibrate or replace the gauges in these sets, gauges have a black-oxide treatment that shows wear patterns. These sets are used to 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.
