Can't bleed radiator in upstairs bathroom

    For some reason, I just can't bleed it. I don't know is the nut rounded or something.

    There's only heat at bottom of it so I know it's full of air.

    I've tried two different tools (pictured below), but both can't latch on to the nut, it's like it's either smaller, or rounded.

    I went to two hardware shops, and both said that radiator bleed nuts and tools are a universal size so didn't have anything to give me to fix it.

    And finally, it's in facing the wall, so I can't access it with any other tools.

    Any ideas what to do?

    Thanks :)

    Yeah those should work.
    You can try to get a camera in behind the radiator to take a snap of the bolt.

    Turn off rad on both sides and drill a small hole at top, use a self tapping screw and washer to seal it, open valves, slacken off screw and allow air to escape.

    Turn Off your boiler.
    Turn off both radiator valves.
    Try to note how many turns the valve that you do not use for adjusting the heat takes to close.
    Drain the radiator.
    Disconnect radiator from valves.
    Take radiator off the wall.
    Remove damaged vent screw with a good pliers.
    Fit new vent screw.
    Refit Radiator to wall.
    Reconnnect radiator valves.
    Open each rad valve for a few moments to allow water into the rad to check you have no leaks at the valve connection.
    Open valves to refill radiator, still checking connections for no leaks.
    Try to set valve you do not use for adjusting the heat back to where it was.
    Open new vent screw to vent air from the radiator
    If your system is a sealed system you will need to top up the water pressure (while filling and) after you have refilled the radiator.
    After filling the radiator, check the water pressure on the system is correct and turn on your boiler to heat the radiator.
    Double check rad valves for any leaks.
