Ohlins steering damper bolt question

Can anyone tell me the specs for these two bolts that belong to a Motocorse Ohlins steering damper kit for an F3 800? Thanks.

They will be metric standard. Measure the ID....

looks like 8 mm and 6 mm from the photo. 6x1.0 and 8x1.25 threads....

length depends on what is being fastened. Head type is up to you, but likely allen (internal hex) type.

I used to be fast....now I just dream about it.

Indeed, M6 and M8 bolts ... Lengths you can simply measure but are not that critical as they won't bottom out so to speak.
I bought the bolts myself and choose for titanium versions.
For your info, I bought the Íhlins used along with the brackets but it lacked the proper bolts so I simply measured it, ordered bolts and made it complete.

I need to add one important detail !
Make sure the M6 bolt that connects the damper clampmount to the top fork plate (see picture) is NOT too long !


So the thread where the finger is pointing at is where the the M6 bolt from the damperclamp enters.
If that is too long it will stick out to far (as it threads through the mount) and it will touch and scrape the bracket that holds one end of the Damper.
So when you steer this will be not as smooth as you'd like and it will have spots where resitance is a lot higher so steering will not be fluid at all.
When you use the proper length this will not happen as there simply isn't enough thread left when tightened and it will not stick out far enough.

Thank you @Dutch MV! Actually in the end, the amazingly nice people at Design Corsa sold me the bolt kit from an existing kit, and they got MotoCrosa to ship them a new set (with a ridiculously long time delay!). So, the bolt they sent was the exact length I needed.
