Philip,
Thanks for posting this.
You said this was only a portion of the list. Is there another size
between 3/8 and 7/16? There's one banjo nut on my clutch slave cylinder
that seems to be in between. An SAE 5/8 (.625) is too small but a 16mm
(~.63) fits (very snugly) so there must be something in here. Or do I
have yet another standard to contend with.
