B12 damper top nut torque setting?

[JSz4]

Does anyone know the torque setting for the top nut on a Bilstein B12 kit damper?

I've had a look at the manual on their website and they give a number of possible settings depending on the nut size which I don't know:

13lb ft if M8
19lb ft if M10
34lb ft if M12
54lb ft if M14
83lb ft if M16

Am I right in thinking you need to get it started with a deep socket-spanner while holding an allen key through the centre, then you can fit the damper to the car and use a torque wrench to tighten to the correct torque as the vehicle weight will stop the shaft spinning?

Thanks for any advice

The actual torque isn't really important, the tightening is just to stop the nut coming undone (which should be a nyloc too) rather than having to exert an exact pressure on the components below.

Tighten as per the thread size (small bolts, less heave) of which that list looks about right (M8, M10 etc refer to the thread diameter in millimeters.)

When I had my e85 struts apart a spark plug socket fitted with an external hex fitted the nut so I held that with a spanner and turned the ram with a long Allen bit.

Thanks Scott, I managed to remove the damper fine but really struggled undoing the top nut. I had a socket welded to a spanner to undo the nut but a 7mm allen key seemed a loose fit so didn't want to end up stripping it so ended up having to take it to a garage who undid it but also chewed up the 'allen key' slot.
