If there is an external thread on the plated
Learn MorePlug Gages While thread gages check the helical structures of a working part, plug gages check whether or not a given dimension (like a hole) is too large or small. These tools look like rods and also have a GO end and a NO-GO end. Again, if the hole has correct dimensions, then the GO end should enter easily while the NO-GO end should be stopped.

Learn MoreLimit gauges are used in inspection because they provide a quick means of checking. The Go and No-Go principals of gauging are that the Go-end of the gauge must go into the feature of the component being checked and the No-Go end must not go into the same feature.
