The Unified Thread Standard (UTS) defines a standard thread form and seriesalong with allowances, tolerances, and designationsfor screw threads commonly used in the United States and Canada.It is the main standard for bolts, nuts, and a wide variety of other threaded fasteners used in these countries. Unit converters 13. WHERE in the supplied information. Mercedes M273 Engine Tuning, 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. Samely, for internal threads, the tolerance of 1B class fitting is larger than it of 2B class fitting by 50%, and by 75% than it of 3B class fitting.

For a class 1 or 2 external, however, I also need to know the allowance, which is available in Machinery's Handbook. The internal UNJ thread will assemble with the standard UN external thread however assembling external UNJ threads with UN series internal threads should be avoided due to potential interference at the minor diameter. Tolerance. BEST INTERNAL THREAD DEPTHS (from UN basic minor dia.) Greg Eagles Dead, The external thread allowance may thus be used = tables = .2121 Max. .0049 = .2224.
