Also known as pin gauges, these Class X plug gauges are used for precision go/no-go measuring of hole sizes and depths, checking hole location and distance, and setting micrometers.

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.

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.

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.

Get your choice of one target-size gauge with 12 larger gauges and 12 smaller gauges, graduated in 0.0001”. Use these sets to measure hole sizes and depths, check hole locations and distance, and set micrometers.

Add a handle to hold your plug gauge. No need for bushings—one handle fits a range of plug gauge sizes.

These gauges come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy.

Ensure the accuracy of NPT thread measurements—these gauges come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy.

Not only were these gauges calibrated in a lab, but they also come with a certificate that's traceable to NIST.

To ensure accuracy of NPT pipe thread measurements, these gauges include a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy.

Join two ring gauges with different sizes to quickly check if threads are within tolerance. Secure your gauges to these holders with the included fasteners.

A true source of measurement, use these gauge blocks to calibrate measuring equipment, mark precise layouts, or position your fixture or machine components just right.

Use the Mitutoyo gauge blocks in these sets individually or together to take precise measurements or calibrate your measuring tools. All come with a certificate traceable to NIST to certify they were calibrated in a lab and meet tight tolerances.

Use the Starrett gauge blocks in these sets individually or together to take precise measurements or calibrate your measuring tools. All have been laboratory calibrated and include NIST traceable certification with the tested measurements.

Often used with go and no-go ring gauges, these holders keep two ring gauges still for quick, repeat measuring.

With a calibration certificate traceable to NIST that says they've passed a test for accuracy, you can trust these gauges to confirm if your object's outer diameter is within tolerance. They're also known as snap gauges because they snap onto rods, shafts, and other cylindrical objects.

Check whether measurements are in tolerance at a glance. LCD backlighting changes from green to red to indicate when measurements fall outside your set tolerance.

These indicators have a larger display than other Mitutoyo electronic indicators for easier reading.

With adjustable magnetic pins that conform to any shape, the base on these variance indicators mounts securely to uneven surfaces.

Adjust joints at the top, middle, and bottom of the base to position the indicator in place. The base is magnetic for a solid mount on metal surfaces.

These indicators can display readings in fractional increments in addition to decimal increments.

Protected from dirty machining environments, these indicators are IP67 rated to seal out dust, coolant, and water from temporary submersion.

Read measurements on an LCD. These Starrett indicators have a spring-loaded plunger that retracts and extends to measure objects.

A contact point on the back makes it easy to read measurements on the LCD from above.
