RAW Hm1000 pellet probe Screw Size.

[Vard]

Update : I ended up tapping out to metric . All good . The only thing is you have to make sure that the grub length is short enough not to stop it going back into the outer .And is also clear of the other grub screws .
Note : the new type RAWs just use threadlock
