Rothenberger torch grub screw seized

[Sonic70]

Hi all,

On my rothenberger superfire 2 the grub screw that you need to remove to replace the piezo has seized in place. I've tried wd40, various Allen keys and torx bits etc but this grub screw won't move. Any one else had this problem and managed to get this screw out?

Pour boiling water or hot air gun.
Metal will expand.
Might help.
Heating metal is a known way to budget things

Thanks, I'll give that a try

Penetration oil/spray or another blow torch to heat it up... Did this the other day on a seized socket for 1" float arm.

Can't use another blow torch as the plastic on off button is right next to it

It's been sitting in wd40 for 3 days now.
