M10 DOME Cylinder NUTS HEX

[mo goldie]

Hi everyone


well sorry about the confusion, what I meant was that the course threads are on the studs NOT the Nuts.
and it is a 1967 Bomber and it has the course studs as I said so it must mean then that they are the 1.50
pitch threads Not 1.25, which is what i got so don`t fit but they did fit the rear shocks so used two anyway 
but still looking for some 8 X 10 mm domes nuts then with a pitch of 1.50 ?

Cheers

Mo

The lower the pitch number the finer the thread.
I think of it as you need more turns with a fine thread to gain the same clamping effect.

Try these.

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.

are ok thanks........... but just ordered the ones from Amazon they were 10 for £4.59

so will try them should be here tomorrow 

[mo goldie]

hi

well that was a waste of time and Money they did Not fit From Amazon... so they are Not 1.50 they must be the 1.25 thread.

Just looked on what Oddjob sent the link for and it was Not clear...... is it 10 for £12.95 or for One ? 

Must be a walking bank I think ha 

[mo goldie]

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 don't understand.

You clearly say in post 15 that the studs thread is 1.50. Yet you go and order 1.25 nuts in your last post from Mr Megapacks.

My link was to Dave Middletons metric domed nuts page, NOT metric fine as those are another page. So those will be 1.50. No idea where you got £12.95 from, they are listed in single price. 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.

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.

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.

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
