I have a couple of barlo radiators where the bleed screw head has become rounded at the top. The brass rad keys do not seem to get a good grip on the head and causing the head to get more and more rounded. Is there a tool similar to the rad key which has various sizes of the square notch within the key. I've got the replacement bleeder screws from barlo. Just need the right tool/key.
Many Thanks,
George
