Brake Rotor Screw Removal! 

I've twisted off two torx tools, one adapted to a hand impact tool, after heated. Next step, Drill baby, drill! I've heard rotors can shatter if hit with a hammer, so glad to see you used a soft face hammer. Thanks for tip on they are not necessary to reinstall. That was my suspicion.

The problem in many cars like Honda people think they are Philipps screws, they are not they are Japanese Industrial Standard (JIS) screws and you need to use a JIS screwdriver which is easy to get.

In my opinion: I would just soak the screw in Marvel Mystery Oil the night before & go for a drive to heat things up before using an impact gun. Heat always is a bad idea because it compromises grease, warps rubber seals & metal parts. It softens parts & annuals them shorting service life. Northern Yankees do dumb stuff like that just like how they pop off exhaust manifold bolts because someone used a torch on a previous repair. If it doesn't work, probably best to drill the head with the smallest bit passing through the inside of the screw & drill off the head. You can remove the rest with an easy out. Striking a bearing hub is always bad because it always spaulds the bearings. It's another reason not to let anyone else work on your breaks because they'd go for the impact driver first because it's the fastest thing.

I've we broken all my Philip heads with this

A little heat makes short work on getting these out

Bro where the beard go 😢
