Mk6 Front brake caliper bleed nipple size

[Tcollings]

Hi guys,

I need to replace the front bleed nipples on my mk6 2001 lwb rwd. I can't find any concrete info online as to the size and pitch of the thread, and I don't want to have to remove them first to check. Anyone happen to know what size they are so I can make sure I order the right ones.

Cheers,

Tom
