Can someone please confirm the thread pitch for inner chainring bolts? I know they're size M8 and I believe the thread pitch is 0.75, but I need confirmation please. And if you're wondering why I need to know the thread pitch rather than just ordering a set of inner chainring bolts from a reputable bike shop, I need an extra long (20mm) bolt to use with a set of Sampson cranks and that length is not readily available.
Thanks in advance for the help.
