I've got a couple of awkward bleed screws. All the screws are direct

As a last resort I'd like to get a stronger key - what should I go
for? Draper Zinc?



Maybe you need one of these?

Personally I would grind/file the open face flatter to improve the grip on
the bleed valve. The actual square socket seems to be quite deeply
recessed.
