Click here to learn more about the Thread Milling system. Therefore a bolt/nut cut to MMC will be As the roots of an external UNJ thread are special semicircles in shape, its minor diameter is slightly larger than it of a regular external UN thread, and that is why it could not match other Inch Screw Threads of the same specifications. = .2175 + .0049 = .2224. (Therefore, if cutting a UN external flat root at MMC the tool must be sharp, absolutely no radius).
