Middletons are very good, usually polished with no visible surface markings.

Plus most 10mm nuts will be 17mm not the usual Honda 14mm, Middletons do the right spanner size.

As an aside Ken, have you thought about exhaust studs in Titanium, like these https://www.ebay.co.uk/itm/114056592306 would be pretty corrosion resistant for bikes.

I've already got stainless ones Nige, like the allen key socket feature though to fit them. The problem I found was getting them the same size as the existing studs, as in the amount of thread on both ends and the right amount of non threaded. I had to compromise a little on my fork bottom studs for instance, they were the correct length but one end had more threads on than the other. I got round it however.
K2-K6:
Thought for the OP, put one of the bike's 8mm bolts beside the 10mm stud so that the threads interlock as that'll act like a thread gauge to tell you if its fine pitch or not.

A 14mm headed domed nut, the correct spanner size BTW for a Honda, are £1.98 each, to buy 8 will cost you £23.21 inc VAT and P&P.
Middletons are NOT the cheapest out there but they are excellent quality and most importantly they are the correct spanner size, 17mm headed nuts on the cylinder head may not even fit, especially if some sit in recesses.

Pretty sure the 450K0 had 17mm AF nuts Ken in that location, borne out by the Service Bulletin. Someone told me that Honda UK imported a massive amount of 450's in one batch in 1966 and because the bikes were unpopular, they were still trying to get rid out of showrooms in the very early 1970's ( seem a few '72 reg's myself) so chances are the bike is pre the iso-thread change. I still need to check my frame for the pitch of the shock mount stud. Another thing on the Bomber was that some 'ordinary' hex nuts were flat on one side and chamfered on the other.
mo goldie:
well what can I say I got it wrong then...........as they must be 1.25 oh well live and learn as they say.............. we all make mistakes...as the dalek said climbing off the dust bin.
we will see how them ones go ha
oh I have checked the shock mounts and they are 1.50 as the new dome nuts fit them fine ;D
