Wheel bolt grade

[Eric Sanborn]

The recent talk of converting to studs (along with having a wheel off 
recently) has got me motivated again to do this on my 4k.  Does anyone 
know what grade the factory wheel bolt is?

I measured the front and it looks like a 50 mm long fully threaded bolt 
will work great.  Won't even have to remove the hub like I did on my 
Rabbit.  McMaster has grade 8.8 (like grade 5) for $80 per 100 (they 
will also break the box for slightly more a piece I would imagine).  
They don't sell grade 12.9 in M14 fine.  I can get them locally however.

Does anyone know the grade used by the factory?

Thanks
