[Roadsters] screw thread size for hitachi carbs

[robert williams]

Hello List,

The ground up resto is in the home straight so looking to finish up a few
smaller items.
Does anyone know the thread size of the following screws:
4 x phillips head screws that fasten the top of the float bowls on the hitachi
carbs
4x screws for the piston pots on the carbs for an early (1966) 1600 low
screen.

I thought they may be 11/32 unf but alas they seem to be a smaller.
The tops of my screws are burred and battered from years of abuse so thought I
would replace them.

regards,

Rob
