WebThread Limit is a standard notation system indicating a level of tolerance for the thread outside the basic thread size of the tap. The limits are identified by a letter "H" for inch or a "D" for metric, followed by a number. Thread limits have been established to provide a choice in the selection of the tap size best suited to produce the class of thread desired.
