Radiator bleed screw

[bikeit]

The radiator bleed screw has rounded and now i cannot get it loose to remove air from the radiator, how can i get the screw loose and can you get replacement screws, its like the one in the link below

There looks to be enough flat surface to grip it with something.
What have you tried already?

That is not the actual bleed screw, i have only tried a bleed screw tool

You could always try a different rad bleeding key, a different type might fit better. But some narrow nosed pliers out to fit. (though getting to it might be challenge, you might need to lift it off the wall and tilt it carefully forward a bit)

I've never tried to buy just the screw, but yoiu can buy replacement units that go in the top of standard rads, I'd imagine one out of the middle of one of those would fit.
