Major Diameter: The maximum When the thread is inspected, it must be passed if the threading pass can be screwed through with the work piece thread, and the threading amount of the stop rule and the work piece thread is less than two thread pitches. Classes of threads are distinguished from each other by the amount of toler-ance or tolerance and allowance specified. Thread series are groups of diameters/pitch combinations distinguished from each other by the number of threads per inch applied to specific diameters. The external thread allowance may thus be used to accommodate the coating thickness on coated parts. 5H, 6H, 6G and 7H for internal threads, and 4H, 6g, 6e, 8g for external threads..
