Hello, Mikey,
I presume the bolts are stainless steel and are being threaded into aluminium. As I don't know the size of the bolts, I can't offer a torque setting, so may I suggest you contact Fanatic direct and ask for their advice (or go onto the USA forum (iWindsurf Community :: View Forum - Windsurfing Discussion) and see what they can offer).
I had a lot of frustration on this, looking for the tension of stainless bolts into aluminium, stainless bolts into stainless heli-coils, TI bolts into aluminium, etc. etc. What I did find is this chart:
www.engineeringtoolbox.com/torque-lubrication-effects-d_1693.html. Except for TI, if you use Tefgel on the bolts, the torque needs to be downgraded. You might care to ask about this if you go to Fanatic.
Not much help, but best I can offer.
