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.

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.

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.

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.

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.

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.
