Hexagon high nuts, style 2, with metric fine pitch thread: the ISO 4033 nut with the same hexagon and height, only the thread differs. Product grade A for threads up to and including M16 and product grade B above. The extra height over the regular ISO 8673 nut gives more thread engagement and better stripping resistance, which is why style 2 is preferred for fine pitch threads. Covers M8 to M39 and includes both the preferred threads and the non-preferred threads.
