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. WebM12 x 25 = 12 mm diameter, coarse thread is assumed (1.75 mm), 25 mm long. M12 is a matching coarse threaded nut. (To avoid confusion, we always include the thread pitch for both coarse and fine metric fasteners.) If you normally work with inch fasteners, pitch can be a little confusing—pitch is the distance between adjacent threads.
