|BBS refers to the company and 10.9 refers to the bolt strength, for what its worth.|
I didn't get a chance to pull a set of bolts out and measure them, but according to what you posted and going off of pertsche has, i would say its likely an M8. I know the head is an 8mm 12point and the nut is a 10mm 12point. Going from the other BBS thread in the mk2 forum, they seemed quite confident its an M8x1.0
right, the 10.9 is the "grade" of the bolt. i just wanted to show that they are BBS bolts. and as for the size, i'm almost 100% sure they are M7's. if you notice on t-t.de's site (main page for wheel bolts), they list a bunch of M7's in varying sizes and flavors, but only offer a few in M8. not to mention, while i can expect a slight variance in the bolt tolerances and my calipers calibration, i doubt there would be a full MM in variance lost. my bet is on the M7.
