Radiator bleed valve keys - Brass/Zinc or other

@news.eternal-september.org:
I've got a couple of awkward bleed screws. All the screws are direct
into the back of the radiator so not easy to get at and I've fractured
a couple of cheapo keys.
As a last resort I'd like to get a stronger key - what should I go
for? Draper Zinc?
With most keys it is better to file of the countersunk lead-in as this
wastes some of the gripping area and prevents you getting further onto the
square of the screw.
+1.
Ive never understood why so many of the brass keys in particular have the
socket countersunk (thus reducing the contact area).
