They are definitely not 24 TPI.
They are (most likely) metric fine 10 x 1 mm the reason I know is because I fitted them to set of Suntour BMX sealed bearing hubs and then recommended them to others who also fitted them.
There's an outside chance they could be 26tpi but I doubt it.
Others have used used 10 x 1 mm as well.

I can't help with the sizing , but the axle nuts that are on my sealed Suntour hubs don't have that flange / spinny washer thingy on 'em .
They look like these type , but a better quality finish ........

Nope 24 tpi I've been around a long time and worked with bikes for many years. The thread is wider than the usual thread. Check with Ålans bmx he will know for sure

Some of the Suntour hubs did come with the track style nuts, that is they had the washer attached.
The nuts from SJS are chrome the ones on ebay are zinc plated.

I'm not questioning your experience but your not right on this one, when I get hold of a thread pitch gauge I'll prove it.

Yep agreed 10 x 1 which explains the coarser thread and the reason that stock nuts didn't fit. Always a joy when companies manufacture different threads and nut sizes lol 1/4" Allen bolts on USA stems etc. means the tool kits twice as heavy as it really ought to be :)
