engine mounting bolts

[Val]

been in simlar position buying bolts recently......one thing i learned, be aware not all bolts are made equal, they all have different properties and will have been chosen for their purpose when the bike was put together, i have in the past purchased bolts that were not OEM but i made sure they were the same material and grade i.e. 8.8, 12.9 A2, etc....there are international standards the allow you to usually detemrine the type and grade of a threaded fastner....

When it comes to parts like engine mount bolts and suspension linkages i would be tending to side with OEM, i don't know enought about the material physics and properties to make the correct informed decisions....but thats just me - i am a little OTT sometimes!

Hi anutz, sorry to hijack the tread, I have a lot of rusty bolts and want to replace them, any chance you can post the sizes and threads and grades for the ones you have bought? And from where?
