Thread Plug Gauges Metric Fine Go/NoGo

The INSIZE metric fine thread plug gauges have a Go and a NoGo side. The Go side must be able to be screwed in threads/threaded holes by hand without applying any force, whereas the NoGo side, which is indicated in red, must not fit in the test item. These gauges are used to check whether the actual thread of a test item is within a specified target range.
