What is a gage?

A gage is any measurement device, such as the following:
  • Ruler
  • Caliper
  • Depth gage
  • Snap gage
  • Go/no-go gage

What is a go/no-go gage?

A go/no-go gage is an attribute gage that quickly distinguishes between good and bad parts. However, a go/no-go gage cannot measure how good or how bad parts are. If you need that type of data, use a gage, such as a caliper, that provides numeric measurements.
