Yes, but WHY list that on a spanner! I have never heard of this before.
UNF sizes specify the dimension across flats on the head of the bolt or
nut, right? And why only list NUT/BOLT for a couple of the spanners.
Finally if you take the 7/16 (NUT) x 9/16 (BOLT) spanner, that would
mean a tiny 7/16 between flats on one end, and a massive 7/8 (is that
right?) between flats on the other end of the spanner. A very wierd
looking spanner. That would make them a combination of Whitworth and UNF
Something like:
7/16 (BOLT) x 1/2 UNF == 7/16W x 1/2UNF
7/16 (NUT) x 9/16 (BOLT) == 7/16UNF x 9/16W
Just to help out, Norman Miller has just sent me an email saying he has
an original toolkit from a Tiger II with AF spanners in it!
Curiouser and curiouser.
