Bilstein shock question

[michowski]

I just got 2 bilstein front shocks. The part number is f4-bes-6215-h5. It didnt come with the nut for the top of the shaft. I have no idea what size nut it is and the instructions are all in german. Does anybody know what size nut it takes?

probably 10 or 12 mm? grab some calipers and measure the shaft, then get a thread pitch gauge and check the pitch. or take it to the hardware store and start trying nuts on it.
