In most situations of manufacturing it is impractical to pull out the old dial caliper and check every dimension on every manufactured part. So specialized tools such as the plug go-no-go gauge, ring go-no-go gauge and the snap go-no-go gauge have been created to increase productivity in quality control.

The plug gauges are used to check whether hole diameters are within their specified tolerances. With the plug go-no-go gauge one side of the gauge is made to fit through a hole being measured (the Go) and side should not fit (NO Go). A progressive type of plug go-no-go gauge has the go and no go diameters on the same side.
Ring gauges are used for measuring external our outside diameters. The go-no-go gauge ring gauges work off of the same idea as the plug go-no-go gauges in that on side of the ring go-no-go gauge is GO, where the part should fit and the other side, NO GO, where the part should not fit.

Snap Gauges serve the same purpose as the ring go-no-go gauges except that they are adjustable and can check the size of both internal and external diameters.
