? W124 rear-axle half-shaft bolts ?

[ke6dcj]

What size are the W124 rear-axle half-shaft bolts (both I6, and V8)?

I think they are XZN triple square, M10 or M12 ? I know they are NOT a Torx head.

BTW: is it best practice to have a separate one for axle/general work and one for cylinder head-bolt work?

Thanks in advance,
