i still got BA taps and dies from schooldays.
Funny that America still use "English" sizes...

Welcome to the forumThank You for this information.
That question dates from 9 years ago but while we're on the subject, odd number BA sizes were much less common but did get some use. FWIW there is still a small market e.g. for rail signal equipment that uses 1BA hardware to maintain backward compatibility.
I have a huge King Dick spanner. Always gets a laugh when I whip it out at parties!King Dick……
Cue childish sniggering from the back…
These folks seem to be selling 13BA nuts:There are certainly odd number sizes, from 1 through 11, then 15 (no 13BA for some reason), here is a small selection of my box of BA taps
Yup suppose I should have checked, it makes sense as it would be 18swg , I just haven't come across one, and was convinced that 13BA was non-existent.These folks seem to be selling 13BA nuts:
13BA Brass Nuts Qty 10 - EKP Supplies - Precision Turned Parts for Model Engineering
EKP Supplies sell engineering tools and model engineering supplies, screw manufacturer,www.ekpsupplies.com
But for sure the odd-number sizes are less common. In fact I can't remember seeing any below 10BA in recent decades.
