Arrrrrgh
Why? Just brought 150 cap headed bolts 12.9 grade to replace the ones on some split rims, torquing them up to 14 lbs/ft and I've snapped about
a dozen of them, but I'm not finding them until I inflat the tyre and check for leeks.
Why are they snapping?

Because 14 ft/lbs is too much unless they are M8 or above.
For M6 you want 12ft/lbs as a maximum.
M5 would be around 7 ft/lbs

Agree, too much torque.

Thanks for the replies, Image Wheels website said 12/14 lb/ft, so I thought tighter the better

If this has only just happened, why is the surface of the break on each bolt rusty?

They look rusty!!
Track days ARE the best thing since sliced bread, until I get a supercharger that is!
