During a Go/NoGo gauge inspection, what should be true about the Go pin?

In a Go/NoGo gauge inspection, the primary purpose of the Go pin is to verify that the part being measured is within the acceptable tolerance limits. For the Go pin to be considered functional, it must fit completely through the hole it is designed to measure. This indicates that the part meets the minimum dimensional requirement, ensuring that it is neither too large nor outside of the acceptable range.

When the Go pin fits through the hole, it confirms that the feature meets the necessary specifications for functionality. This process is critical in manufacturing and assembly, as it helps maintain consistency and quality in the components used. If the Go pin fits snugly or loosely, or does not fit at all, it indicates that the part has dimensions that do not conform to the required standards, which can lead to performance issues in the final assembly.
