Here's a really helpful older thread...

Although I thought the retaining bolt was 5/16 Cycle thread (26 tpi, 60 degrees). Above it's listed as 5/16 brass (26 tpi, 55 degrees). Not sure which is correct.

I have just been out to have another look. I think you may be correct.
55 degrees is close but not quite right. I don't have a 60 degree 26tpi guage to check.
I will amend the other thread.
