Electra stud


I have a 1963 Norton Electra.

One of the breaker point pillar bolts has broken off.

I removed the remains, filled the hole, and have ordered new studs.

Question is what size tap do I use to rethread the hole?

Anybody know that?

Many thanks.


I’m pretty sure the pillar bolts are the same as the commando, not that I know the thread type, although I’d guess BA but you could meathure them when they arrive?! 



2BA is the size you are looking for.



Here is a photo (not to scale) with dimensions.

From memory - the Commado one is different & cannot be used (I tried).
