Windscreen visor thread size?

[kevchard]

Hi
Can anyone suggest what the thread size / pitch is for the windscreen visor on a cobra. This is the threaded hole in the top of the winscreen chrome frame. I think the screen is Brasscraft or Autobrass. It is probably about 10 years old aswell if that helps.
If no one can come up with a definitive answer, then metric, imperial, UNC, UNF would be a help.
Cheers
Kevin

Im not 100% sure whether it will be a 2ba or 4ba thread. If its brasscraft or Autobrass it will definately be a ba thread.

Pilgrim are the only ones I know of whose screens use a metric thread.

All I know is they are microscopic little beggers lol.

Yup - BA threads, can't recall if they are 2 or 4 ba.

its slowly coming back to me, I think teh sun visors and windscreen centre stay are 2ba and wind wings /side pillars are 4ba

either way its ba.

2BA on the pillar bolts and 4BA on the Sun Visor/Hood Bow catches

As ever i am forever in your debt. I will nip down condescending hardware shop tomorrow and get a set of 4BA countersunk screws.
I looked on Europa site and they list the sun visors with a fitting kit that has the code 4BA in it. So this more than backs up your words of wisdom .
Thanks again Anthony, Wilf and Chris.
