Class Z Go Plug Gauges
Use these Class Z go gauges to check the minimum hole diameter. Also known as pin gauges, they help you measure hole size and depth, 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.

Class Z No-Go Plug Gauges
These Class Z no-go gauges help you check the maximum hole diameter. Commonly known as pin gauges, use them to measure hole size and depth, 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 no-go gauge is unable to enter the hole and a go gauge can, the hole is within tolerance.

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 Gauge Sets
With Case
With Cabinet
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 Z gauges are the most common. You'll often find them used on shop floors.

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.
