Wear-Recognition Go Plug Gauges
A black-oxide treatment on these go gauges shows wear patterns so you can tell when you need to calibrate or replace the gauge—use them to check to minimum hole diameter. They help you measure hole sizes and depths, check hole location and distance, and set micrometers. 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.

Wear-Recognition No-Go Plug Gauges
The black-oxide treatment on these no-go gauges shows wear patterns so you can tell when you need to calibrate or replace the gauge—they help you check the maximum hole diameter. Use them to measure hole sizes and depths, check hole location and distance, and set micrometers. They come with a certificate of accuracy traceable to NIST that states they’ve passed a test for accuracy.
If a no-go gauge is unable to enter the hole and a go gauge can, the hole is within tolerance.

Plug Gauge Sets
With Case
Keep dozens of plug gauges on hand to check a range of hole sizes. You’ll often hear them called pin gauges. Use them to measure hole size and depth with precise go/no-go tests, check hole location and distance, and set micrometers. Sets include a manufacturer's certificate of accuracy to certify diameters are within tolerance. Gauges are tool steel, so they’re strong, hard, and resist wear.
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.
Choose a class based on the level of precision you need—the smaller the tolerance, the greater the accuracy. Classes are based on ASME standard B89.1.5, which states diameter won’t vary more than the listed plug gauge tolerance. Class ZZ gauges are ideal for quick checks that don't require extreme precision.
Black-oxide tool steel gauges show wear patterns, so you know when to calibrate or replace them.
