Bolts holding Starter Switch

[SavannahDog]

Hi, I,m trying to understand the bolt size holding the Starter Switch. 2BA is too large. Buy the way whats BA stand for anyway.

BA stands for British fastening before witworth.. Managed to purchase some 00, and 01 both from BA Bolts in England.

BA stands for British Association. See here https://en.wikipedia.org/wiki/British_A ... ew_threads

I believe the screws are 4BA, 1/4" long.

They are indeed 4BA, with slotted hexagon heads. Originally they had little tab washers with an ear bent up to stop them loosening. I know this because I have an unused ST1 switch in its Lucas box, with a little packet of screws & tabs.
The thing about BA is they were not originally British at all, but a Swiss Metric watchmakers thread! Because of this, 0BA, the largest, is exactly the same diameter & pitch as M6.

OK I've bought 2BA bolts and their too big. Maybe my starter is not original but I ordered 2 and 1. Well see when they get here.

Well My BA 1 and 0 were too big. And this proves it https://en.wikipedia.org/wiki/British_A ... rew_thread

I'll try American sizes.

Roger, Sure could use them. Thought I could buy what I needed. But I'm failing at that.

If you could Please send me 2 two of the screws.
