    point is he can’t get the carpet out of the way, it’s pinched between the plate and the floor.

    that will not need heated

    hit it hard with a decent air impact & it'll spin right out

    those bolts have oblong threads

    Dirt and rust??? I can tell that most of you guys don't live in the salt belt..... that's pretty clean by Western NY standards.

    Heat it up, back it out.

    As mentioned...penetrating oil is helpful...cleaning up the thread that you will be twisting out of the hole is helpful. I would try an impact driver mixed with these two at first. If the torx head fails you, maybe you can have a friend tack weld a nut on the head, or just drill it out at that point. If you are concerned about heat and the carpet, putting a couple of layers of aluminum foil between the floor and carpet might help, or a skinny piece of sheet metal.

    PB blaster....then an IMPACT DRIVER....not an impact wrench...not a long wrench with pipe...but an impact DRIVER.
    It does 2 things simultaneously!
    1st it translates your hammer blow into a rotational movement (full stroke = about 1/4 turn)
    2nd it also HITS the bolt vertically (which has proven to be a GOOD thing on BAD bolts)

    another method as mentioned ...sort of ...is take a 4" grinder and grind OFF all the bolt threads sticking OUT OF THE NUT PLATE underneath. This will HEAT the bolt AND get rid of "unwanted" threads that must go back up thru the nut plate.

    Good luck....those things can be a real pita

    Yes. Make sure you have the exact right size torx and hit it hard with a good impact. Hard to find a decent air impact anymore. If you can borrow a big milwaukee cordless 1/2 impact, the bolt does not stand a chance.

    Trick i have used is to tighten then loosen the bolt several times "back and forth rocking motion" along with PB Blaster.
