J screw threads feature a root radius which improves the tensile stress area of the fastener and helps to reduce the stress concentration factor in the thread thus making the thread stronger. One, it makes it possible to calculate screw threads based on arbitrary combinations of Nominal Size and Threads Per Inch. The only difference between a UN internal and a UNJ internal thread is that the minor diameter of a UNJ internal is increased by .054127P X 2. 1/2 - 13 UNC - 2B Thread Engineering Data Chart. Thread Information system 22. (Imagine a cylinder on which the bottoms of the threads lie. Therefore, 3A/3B thread fitting is usually seen in crucial design with safety requirement in commercial or aerospace industry products. The internal thread does not get the same rounded root treatment because the internal thread usually has more mass around the thread and is nearly impervious to stress fracturing. 1A and 1B: Refers to the thread fitting with the most loose tolerance, where there is a huge allowance. External UNJ threads per SAE AS8879 have a rounded controlled root Engineering Standards With these enlarged radii, minor diameters of external thread increase and intrude beyond the basic profile of the UN and UNR thread forms. Example: The recommended H limit for a 1/4 20 UNC 2B would be GH5 and for a 3B it would be GH3. DIA= Diameter radius). AN= American National
