Hi. I lost a part ( hex nut) probably due to the vibrations of my EFI B5 Standard 2017 and I find hard to get the right part off the Parts Book Online were I can only detect a Hex Nut with size M10 1.5 but that look metric to me and the bar measure half inch in dia? I manage to find ( im in Italy ) a 1/2 UFC Nut but it does not fit .. Any help? Thanks https://postimg.cc/bsh4ssqr

12mm? measure the diameter with verniers and measure the pitch with a thread gauge, then you will know exactly what you have.

Thanks, I think I managed to find the part to be HEX 1/2 CEI ( 26tpi ..?)

Yes, some parts of my Indian Home market 350 have a cycle thread, which is very slightly different to metric.
The rear seat fixing studs and nuts are one example of 26 tpi threads.

Just to catch the unwary and make things more difficult, I reckon....can’t think of any other reason, most things on my bike seem to have metric threads.

I think you need part number

110365

And also washer part number

586037

A phone call or email to our hosts will be a good idea to make sure

7/16 thread

Think I got it right

Thanks, this is a EURO 4 so I'm baffled regards this choice of Threads for such a part
