Go no go gages are made in a variety of types and sizes. Some of the most common are pin gauges or plug gauges. Used to determine the diameter of a cylindrical hole or bore, these gauges work similar to a bore gauge, except in “go/no-go” fashion.

Pin Gages

Rather than taking an “as-found” reading with a gauge, the user places the “go” gage in the opening to check that it fits, and does the same with the “no-go”. Based on the difference in size of the two gages and the grading, this method helps the user determine whether or not the bore is within any acceptable tolerances.

Since pin and plug gages can wear down over time, it’s important to have them verified regularly, dependent on frequency of use. J.A. King offers NIST traceable pin and plug gage calibration using master standards such as universal length measurement machines and comparators to help ensure your checks are correct.

We can even offer solutions for performing quick checks on gages such as the pin gauge classifier built by our engineering department.
