What size hex key for the Innokin Axiom

[Bocavapor]

Hi everyone!!

I received my new Axiom tank last week and was really disappointed that they didn't include a hex key for the RBA! All the reviews said the full retail version would have it...I contacted Innokin and they said no...and not much help after that...UGH!!
The hex key I have is a bit too big from my coil master kit, so does anyone know exactly what size hex key I need??? I want to build on this so bad...and I can even get the screws up!!!

HELP!!!

If the grub screw is a M2.5 the hex key size will be 1.3 mm

If the grub screw size is a M3 the hex key size will be 1.5 mm

Thanks Jim!!

The CS person at Innokin said the screws were M3.0*0.5

The hex key I have from my coil master looks like 1.5, but of course is not marked and too big. I'm going t see if I can track down both sizes.

Thanks again!
