Currently sorting out my boxes of various fasteners from when I removed my cylinder head & top covers. Most of my covers had SS Hex head bolts fitted previously.
In a box I marked Cylinder Head Nuts I have 8 flanged flat face M8 nuts, 2 of M8 chrome domed nuts, 4 of SS M8 nuts, 12 of M8 flat washers.
The manual shows 12 of M8 flat faced flanged nuts (90236-300-000) so the SS nuts were probably a substitute for 4 missing ones - not sure where the domed nuts go as I can't see them in the parts book.
The DS price for the flanged nuts is £2.88 each, looking at alternative nuts on e-bay it appears some M8 nuts have a larger diameter flange so probably would not fit in the recess.
Are there more sensibly priced nuts available that are suitable to replace the originals ?
Lastly the 6 rubber caps that are glued in place - what is the best adhesive to use for these please ?

They should be high tensile steel nuts with a thick washer under them have loads of them on my stock list.
You stick the rubbers head sealing pucks down with a smear of honda bond on the rim of the rubber to the underside only ;)

The parts manual picture shows flanged nuts plus washer, although the description makes no mention of the nuts being flanged.
DS show it as a flanged nut.

90236-300-000 is a CB750 part which why would it say its flanged. It is used on many Honda head studs :o

I suspect the owner before me put the stainless domed nuts on the outside 4 studs for appearance sake, i know there were a lot of stainless cap screws visible
The nuts should be flanged as Trigger said but not the serated type flange that is common to get only flat flange.

And are only 60p when you buy them in a big Honda trade pack ;)

A much more sensible price is 60p each.
