Hello again
Does anyone know the size of the nut that holds on the steering wheel?

.............. and on a 6, 6A, 6B, Robin, and Rialto. And probably a few more.

Should have been clearer. It's the thread size I need, car came without one! (GTC)

Thinking positively - just suppose you only had the nut and had to find all the other bits to make the GTC! :shock:

Thanks all, I'll get on to it.
This is one of the easier things I've found missing - see my thread in 'wanted' section! http://www.scimitarweb.co.uk/sgwrs/view ... 22&t=36047

Something odd going on here. The new 9/16 UNF nut arrived today and - it doesn't fit!! The thread on the column is much finer, hope you can see in the photo -

and the new one is only 7/8 AF not 15/16. That old nut is from a SE5, it's the same as a 6a. All three columns have the same fine thread.

I've been doing some research on the web and there's a thread called UNS which has 32 threads per inch and that's what I think the column has, from my rough and ready measurements. Seem hard to come by though, I'll see if Nigel at QRG has one next time I'm ordering.

Nigel says that the nut and in fact the whole column is a Reliant special from the early 3-wheeler days! He's going to get some nuts made up.

Wish I'd known that yesterday! I feel I should support Nigel if he's good enough to get parts made.

BTW have you seen my 'wanted' list? http://scimitarweb.co.uk/sgwrs/viewtopi ... 22&t=36047

Are you sure it's not the same as a Triumph steering column nut?
e.g. Herald, Spitfire, TR4, TR5, etc

I can't find anything to say what thread they are, but lots of comments about being a very fine thread, and the picture looks very similar

I believe the Scimitar one is 28tpi which is another of the 9/16 UNS ("Special") threads. I've no idea what the triumph one is though.
