Technical Punto GT front calipers - threadsize of nipple

[MKoers]

I got some GT calipers on my Seic but the bleed nipples are worn.
I have to open and close them with a grip tool so no the best way to do it.
I want to get some new ones but haven't found them yet.

Does anyone know what threadsize these things have?

It should be m8 x 1.25 (I was looking into doing up a set myself).

Any firm doing brake re-cons should stock suitable ones (brakes uk, maybe?). Folk were doing stainless ones for bikes, so maybe there's something out there. 6 sided sockets/spanners are your friends.
