bolt type on axles

Does anyone know the type of head on the 6 bolts that are holding the axles to the differential on a 1999 MK4 GTI 2.0 AEG engine code?

Looks like a Torx set bit. The cheapo repair manual says its either an M8 or M10, but im interested in the type of head.

Thanks

if anyone cares.

Checker had a set called a 12 point star internal wrench set.

hope its easy to replace the dam half shaft.
