Hi
To the best of my knowledge, the "Across Flats" spanner size for prewar A7 3/8 BSF wheel nuts is 19/32 inch or 0.59375 inches or 15.08125 mm
My 15mm twelve point metric socket is theoretically 0.003 inches too small, but it fits happily.
However, I normally use a "proper" A7 wheelbrace, and have a collection of BSF and BSW spanners and sockets culled cheaply from the local car boot sale.
