UN BASIC MINOR DIA. UNK- same as UNR except the minor diameter of the external thread is toleranced and This method requires knowing what tap H limit that is recommended for the thread class of fit (2B 3B etc.) Glass Marbles Walmart, :21-41A, 6 June 2003). MIL-S-8879 was primarily thought of an used for aerospace fastener and threaded component applications. Using the "Easy Memory Chart" (see the drawings to clarify), I can accurately cut a UN class 3 external thread and know that is correct and will fit without having to use a gage or any tables. is the minor diameter.
