Need to disassemble a motor (see cooling fan thread) which is held
together by four long machine screws with a head that I have never seen
before. Imagine a slotted machine screw but with a 'slot' that is raised
rather than sunken. Anyone come across this before? Does it have a name?

There are umpteen types of tamper resistant screw head available. This may
be a custom one made solely by the motor manufacturer. I'm sure you can
hacksaw or file a matching slot in something you can then drive with a
socket or similar. A bit of scrap bar with the slot at one end and a cross
hole drilled through it at the other to take a tommy bar would suffice. You
might even be able to just grip the ridge on the screw with mole grips if
it's high enough.
