Are bleed keys all the same size?

Older bleed keys were imperial equivalent to 4.8mm (key size 12) . After metrication they were rounded up. Although the intention is to make them to the same standard size, manufacturing tolerances can be different as are materials used. Both can affect performance especially if the valves are tight. If the key slips round use long nose pliers.

Will these wind a napoleon hat clock up as clock was my grandparents & the key was lost

Definitely not! Go to a clock repair shop or check ebay. They cost around a fiver.

Will this fit a standard house radiator

Hi, Yes it is a standard radiator key. Thank you.

Will these work on most radiators and could someone advise how to bleed? Thanks in advance

I think they're universal. Just put the key on the screw at the top of the radiator at the side. Turn the key until any air stops hissing out and quickly turn they key back when water comes through. If I can do it, you can!
