Plug Gauges for Inside Diameters

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.

Class X Plug Gauges

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.

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.

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.

Metric Class X Plug Gauges

Use these metric Class X plug gauges for precision go/no-go measuring of hole sizes and depths, checking hole location and distance, and setting micrometers. They’re also called pin gauges.

Class ZZ Plug Gauges

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

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.

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.

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.

Plug Gauge Sets

Take precision go/no-go measurements of hole sizes and depths, check hole location and distance, and set micrometers.

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.

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.

Plug Gauge Handles

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

Threaded Plug Gauges for Internal Threads

Threaded Plug Gauges

These have a go gauge on one end and a no-go gauge on the other end.

Threaded Plug Gauges with Calibration Certificate

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

Threaded Plug Gauges for NPT Pipe Threads

A notch on the handle indicates when the internal NPT threads you’re checking are in tolerance.

Threaded Plug Gauges for NPT Pipe
Threads with Calibration Certificate

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.

Tire Tread Gauges

Ensure tires are fit for use. Gauges measure tread depth up to 1".
