Actually, I once saw screws which looked a bit like
Robertson (the
square-socket kind) but with a triangular, not square, socket. I think
they were intended as a "security" screw head; I just took a spare
Those turn up on cheap domestic appliances over here. The only possile
reason for them is to make the device difficult to repair, something
which, not suprisingly, I disapprove of.
I've not managed to fidn a source of drivers or bits for these in the UK
-- the 'security bit' sets don't contain them, and none of the tool shops
I frequent keeps them. Does anyone know a source. So far I've had to make
my own drivers from metal rod, fortunately the screws haven't been that
tight.
