It is argued that fine tuning of a minimal set of parameters, needed to fix the hierarchy of gauge-boson masses and a knowledge of intermediate symmetry groups, leads to ''natural'' mass scales for physical Higgs bosons in grand unified theories. This is applied to ..delta..B = 2 transitions in models based on SU(5), SO(10), SU(16), and (SU(2N))/sup 4/. It turns out that the Higgs bosons which mediate ..delta..B = 2 neutron-antineutron and hydrogen-antihydrogen oscillations become superheavy, and so such transitions can be observable only in theories with low unification scales, such as SU(16) and (SU(8))/sup 4/, if we adhere to the hypothesis of minimal fine tuning.
