Plug & Pin Gauges are precision tools designed for verifying the dimensional accuracy of bores and holes. These solid, unthreaded steel rods perform essential Go/No-Go tolerance checks, ensuring parts meet specified size criteria. A 'Go' gauge confirms the minimum acceptable size, while a 'No-Go' gauge checks the maximum. Available in various classes, including Class ZZ for general use with optional corrosion-resistant coatings, and Class X for applications demanding higher precision.
