These are very badly made with a circular shaft with very shallow notches to grip corners of the SQUARE bleed valve. A ridiculous design that wouldn't touch the corners of any old radiators, and managed to round the corners slightly on newer ones.
Save your money and time, go and get a pair of Rothenberger ones, though even they will need the end filing down in order to grip older valves (as would these [tried, tested, binned] and the equally awful Plumbsure keys).

I purchased this as a spare. What can I say? It is cheap and it works well. It looks as though it will last a while too.

Ok for bleeding most valves but no use if valve is too tight (too small and therefore cannot get any purchase)

This key simply doesn't work with any bleed valves in my house. The problem is that the hole in the centre of the key has been made with a circular drill and then four angular corners have been made in the inside of the drill hole. I think the idea is that the corners of your square headed bleed valve would then sit in those cylinder corners and that should do the trick. This might be the case if your bleed valves are brand new, but if they are old valves that have been opened a few times, the chances are that the square valve top has probably been rounded off a bit and these keys will then simply spin round.
In a nutshell, these keys might be OK for new or pristine bleed valves, otherwise avoid!
