Plug Gauges

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.

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.

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

Keep dozens of plug gauges on hand to check a range of hole sizes. You’ll often hear them called pin gauges.

Threaded Plug Gauges for Internal Threads

Go/No-Go Threaded Plug Gauges with Handle

Speed up thread tolerance checks—the handle on these gauges gives you a good grip to quickly thread and unthread go or no-go gauges.

Go/No-Go Left-Hand Threaded
Plug Gauges with Handle

A go and no-go gauge in one, these gauges check that left-hand threads fall within tolerance.

Threaded Plug Gauge Handles

Speed up checking thread tolerances by threading a go gauge on one end of these handles and a no-go gauge on the other.

Threaded Plug Gauges

Test if internal threads fall within tolerance.

Battery-Powered Pistol-Grip
Drivers for Threaded Plug Gauges

Test thread tolerance in seconds. A time-saver for high-volume work, these drivers quickly thread gauges in and out of holes for you—just pull the trigger.

Go/No-Go Hex Plug Gauges with Handle

Confirm hex drives on socket head screws are within tolerance.
