Thread & pitch size

[adreamin]

After inspection of the om617 kkk wastegate I believe my 10mm locking nut is missing explaining a lot of issues I've been seeing.
Anyone know the size and type it is.
Thank you

Don't suppose you know the pitch?
So far I've been told 6mm x 1.
but not sure if is a .25 or .50

Thanks for the reply too

Per your statement above, the size is "10mm", and the type is "locking nut".

It may be of some help if you can decide between 10mm, and 6mm.

I'll be getting it tomorrow n kinda confused
Reading about putting one back on I've read use a 10mm socket, also believe it's a 6mm bolt though no thread pitch is mentioned, being rusty n corroded using a locking nut I'm looking for the correct pitch not to mess the threads up,
I really really don't wish to mess this up, be afully expensive mistake and very time consuming repair.
Thanks again

6mm fine or 6mm coarse is the diameter and pitch of the bolt body and 10mm is the side of the bolt hex head.

6mm x 1.0mm is the fine thread.

Thank you, not a mechanic yet but working on it.

Back to reading on getting it to correct

Bolts are spec'd out by the thread diameter-so I think you're looking for a M6x1 (probably what you need-the most common 6mm size)
