Clutch screw M8 x 1.0 (fine pitch) x 16 slotted head

Replace these every time you reassemble the clutch. You'll be glad you did.

If your 2011-and-older Ural still has the original flywheel, it should use these fine-pitch M8 screws. If the old screws have slotted heads, then they are almost certainly M8 x 1.0 fine pitch. But check them using a thread gauge to make sure.

Apply medium strength thread locking compound, aka "blue Loctite", prior to assembly. And if you want you can still peen the heads against the thrust plate, too.

We haven't found a cheaper source for these that we trust -- McMaster-Carr's only match is a stainless bolt that costs $7.80 each.
