heat for seatbelt torx

[Dirtfarmer]

If it is loctite'd in you will need heat to release it

Drilling these are a PITA as they are hardened bolts. Angle grinder to make to flat spots in the sides and then use a BIG pipe or adjustable wrench to get them off. The heat from grining helps break the bond of corrosion and the factory lock tight. Anyway that you do these, they are NOT fun.

yeah you can't drill them

T 47 is the correct one. I took a grinder to some my son jacked on his mustang doing the same thing. I flattened a hexagonal configuration & used a socket & breaker bar to remove they are very tight regardless of heat.
I've actually been able to use a T47 after one was stripped to get it out unless it was mangled.
I've also flattened 2 side & used a 36 inch pipe wrench. Bunches have used the wrong size including me. The right quality socket & a breaker bar is the facto way to remove. You can put tons of pressure on them. I never had any luck with the Hammer impact tools. An electric impact may work but I have always used a breaker bar & T 47. 1/2" drive No Harbor freight stuff.
I've broken sockets & stripped bolts learning the hard way.
The bolts are hardened so drilling is going to destroy some bits & still get you in worse trouble. It will remove the only hope you have in getting it out when you drill off the head. Don't drill the heads off this is an absolute last resort. This will just make them harder to get out.

Edit
I didn't see FSJ-EARLS post I agree but use a pipe wrench cresent is a waste.

A carbide bit will make short work of drilling through the bolts (if you need to).

I had had all else fail, and finally drilled it out and Heli-Coiled it back to 7/16-20.

I was lucky. The ones in my 77' Cherokee came right out using just a 3/8" ratchet.

Yeah NO

Actually a T-50. Never ran across a 47, 45 and 50, yes, 27 yes.

Really Seek the truth:
