Robert!
UNF is Unified National Fine. #10-32, 1/4-24 etc.
UNC is Unified National Coarse. #10-24, 1/4-20 etc.
The British, at least BMC, used a lot of UNF threads. I think it
matched close one of their many own threads. The only things which
arn't UNF are the fastners on the carberators.
Catch you later
