14 gauge = .080"
13 gauge = .092" for 14 gauge ***s threaded for 13 gauge spokes
(This one fits on the 14 gauge ***s tighter than normal, so the
square surfaces are harder to round off with torque.)
12 gauge = .105"
For 13 gauge spokes, it is better to have 12 gauge ***s than 14 gauge
***s, since the 14 gauge ***s are too easy to round off, even with
the proper spoke wrench.
I have the three above plus one that fits the old Miyata ***s, but I
don't know off-hand what size it is (probably somewhere between 13 & 14
