For plug gages a plus tolerance is applied to the GO member and a minus tolerance is applied to the No Go member. Now lets talk about the NOGO gage. According to a Peter's Principal; the GO gage must check all the product features in the maximum material condition. This method assures that nothing beyond the product tolerance is passed by the gage. /Font <> Input Data and Result are rounded to 8 decimal places. Combination go/no-go plug gauges Go plug gauges and no-go plug gauges are called single-ended gauges and consist of a handle into which a precisely machined pin or shaft has been inserted (sometimes called a member) and which is used to verify an aspect of the dimensional tolerances of the hole. Ensure proper tolerances are met with OSG precision ground Plug Go and No Go gages. This time we will talk about a shaft with a size of 0.501"/0.511" and a hole with a size of 0.512"/0.522". Great!
