Not my doing but one of the screws in tap is seized and head destroyed.
I have carefully tried various cross head bits and needle nose pliers.
I have currently sprayed with lub to soak overnight.
Access is not good as it is recessed by 12mm and the dimaeter of the
access point is 12mm.
My next attempt would be to drill out but want to leave that as a last
option. So any other ideas to explore first?
Made harder by being sunken in the shroud... You might be able to create
a couple of flats on either side with a needle file, then get pliers on
it. You could also try some thermal shock - hold a bolt with pliers, and
heat the end blow torch and then push it onto the end of the screw for a
bit before trying to turn it.
Personally I would probably try an anticlockwise drill bit just slightly
larger than the size of hole already in it. It will either grab and spin
it out, and if not, it will take the head off, meaning you can remove
the tap handle and then worry about the shank of the screw after.
The larger picture appear to show that there is some of the cross head left.
I have a cross head screwdriver where the point of the cross head has
been filed off so it doesn't bottom in the screw head when attempting
just to catch on the edges where remnants of the cross head may give the
screwdriver some grip.
If drilling - use a drill with a larger diameter than the head of the
screw and JUST drill the head off - leave the rest of the screw intact.
You should than be able to remove the tap head and have the rest of the
screw standing proud of what it is screwed into with easy access to use
mole grips to get it out.
Its more an impression from the shadows nothing of the crosshead left. I
will try and file a bit though and give it a go.
I am only trying to save the taps as a neighbour wants them from when I
replaced my bath with a shower tray.

Dont have one but could I suppose try using cordless drill on hammer,
has worked before for me. OR if needs be use a crosshead bit and thump
it with a hammer.
I will look at all suggestions and go from gentle to not so gentle and
then destructive, assuming if I destroy the screw head then the shroud
will come off and then can tackle the remains of the screw, which by
then will give me better access.
I'd try an impact driver like one of these, You hit it with a hammer
Not enough space for multi tool.
I eventually drilled off the screw head and had another screw that fits
from an old tap, so problem solved.
As it turns out the reason it was seized was the screw was actually bent
and had been forced home, the new screw works ok so the threads have not
