Trying to find correct size chainring bolts

One of our bikes has internal gearing (Nexus) and obviously single
chainring
up front... there is a metal chainguard attached to that chainring and I
need to replace the chainring bolts. However... I need bolts which feature
a
nut (the female part) of length 10mm in order that thickness of the
chainring/crank arm/chainguard is properly covered. Am finding it near to
impossible online to find the ones I need - mostly due to fact that very
few
retailers bother putting dimensions in their descriptions. Any longer than
10mm will be too long and will mean I will not be able to tighten them -
need to be 10mm.

A search for 10mm bolts or double crankset bolts--which is what you
need, turns up numerous options. Google harder.

...believe me, I have googled plenty hard - I think you
are probably seeing
results for 10mm DIAMETER rather than length. I think I
have found ONE
supplier of what appear to be oversized (13mm total
length) which would
mean, sadly, a millimetre too much by the time you take
off a mm for the
heads of the nut and bolt which sit proud of the each
side of the
chainring..



Standard chainring bolts are m8x1.0 thread in a 10mm
diameter sleeve.
Double ring nuts are 8mm long, the old ATT triple sleeves
are 14mm long.

I believe you are looking for standard 8mm nuts with m8x1
bolts. What crank is it?
