Masters and Setting Gages

While similar to other gages in that they help to set and determine gauging standards, masters gages and setting gages are not used with other specific devices, instruments and sensors. Instead, masters gages and setting gages provide dimensional standards for calibrating other gages.  Masters gages and setting gages are designed to variety of tolerance grades in both metric and English dimensions. Gage blocks, end measuring rods, setting plugs, setting discs, setting rings, and thread standards are masters gages and setting gages that fit into this category.
