This verification would be performed by threading the Go thread gage to the full depth of the feature without restriction, followed by the non-acceptance of the No-Go plug gage. Notes: A tap cannot produce a class of thread it can produce a tapped hole within specific product limits. A problem that sometimes occurs is that on long thread engagements (that are frequently used for tapped holes in soft materials) there can be an interference between the nut thread and the screw thread as the screw is rotated into the tapped hole. View Comparison.
