Thread Limits. thread limit is a standard notation system indicating a level of tolerance for the thread outside the basic thread size of the tap. the recommended h limits found in manufacturers’ catalogs and other industry literature, are based on it being at approximately 40% into the tolerance zone for the class of fit. normal tap tolerance is iso 2 (6h), which generates an average quality fit between screw thread and nut. there are (3) established classes of thread, designated in the unified series by adding: 95 rows ansi/ asme internal screw thread size chart. A for screws and b for nuts (or other. In some cases it may be slightly more or less than the 40%. The limits are identified by a. h and l limits are used for inch size ground thread taps. these are general tap recommendations to produce the class of thread indicated in average materials when used with. H (high) represents a pitch diameter that is larger than the basic pitch. All units are in inches.
