Skoti, great price but postage too high @ £24 (works out same total price as new Honda from Silvers)
Ken, good point, wasn't bothered about 12mm originality but never thought about the socket issue.
I think in light of all the variants in the nut make up/design/strength/etc as discussed in this thread, I'm going to re-zinc the existing nuts to be on the safe side. Good debate though and learned a lot - hopefully been beneficial to other members too. Thanks for all the input and advice.

Just get out in the cold and re plate  And don't forget to do the stud washers

so mine are 13mm stainless on my 550 and my socket fitted fine.

I know, I know! I'm in the garage anyway Graham plating the crankcase bolts but the nuts and washers are fiddly to de-rust compared to bolts

Thanks Mick - I'm more bothered about the other unknowns thrown up by other members and internet research, Although, to be honest, within the constraints of the way I would be riding the bike, I don't think I would have any issues.
