Quick Summary

A flush-pin gauge is a type of measurement device used in manufacturing and engineering. It is a fixed-type gauge, meaning it indicates whether a dimension is larger or smaller than a reference standard, rather than measuring the exact size. Specifically, flush-pin gauges are used to measure the depth of shoulders or holes and have only one moving part.12

Gauges, in general, are instruments that determine if a dimension is within a specified tolerance range. They can operate mechanically or electrically and are crucial for ensuring parts meet precise specifications.2
