If you look down the A5 thread starter Page you will see this
Front wheel hub triple square bolt torque value (
1 2)
You can reuse the 6 point which is 10.9 and is not a stretch bolt but because of
it is a critical component should be replaced as stated by Bently. If you read my last
you will see why I was not able to use my bolt charts to compare the 6 point to the
8.8 12 point. By the way I believe the 12 point is an external xyz(triple square) and
a proper fitting socket will probably not break along with a 2 foot 1/2 inch breaker bar
with a pipe on it. My own feelings is the correct torque is 200 NM plus 1/2 turn and
the 8.8 12 pt. is now a stretch bolt that must be replaced. I think Indigobluewagon
is correct inpointing out what is correct torque figures for the 12 pt 8.8
Edit: As you can see meechm ended up with 340 ft lbs which was 200 NM plus 1/4 turn
and I think 180 NM plus 1/2 turn would be in the same area of torque. I hope my explaination
in my last post explains why the high torque compared to the 6 pt and yet the same result
may result. As I point out in my last post friction at the 200 NM torque point will effect
the start point of the 1/2 turn and the integral washer may affect this initial friction by a factor of 1.5.
So it is critical to start with all surfaces dry.
That said I feel uneasy with these unverified figures and feel that they should somehow be confirmed officially.
