Wear-Recognition 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.
