Clutch screw DIN 7991 M8 x 16 Class 10.9 black oxide finish

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

The factory screws are treated with a thread locking compound called Precote 85, but Ural rarely has them in stock, so we use these screws as an alternative.

Apply medium strength thread locking compound, aka "blue Loctite", prior to assembly.

Threads are M8 x 1.25 pitch,  per the DIN 7991 specification, and the screws are metric Class 10.9, per Ural's spec.

Older Ural flywheels with the slotted-head screws will require M8 x 1.0 screws.
