Need to disassemble a motor (see cooling fan thread) which is held

a name?

Maplins usually sell them:

tabid=1&criteria=usb&c=so&u=strat15 but also search for security screwdrivers on eBay.
Any idea which out of that set is the raised slot? Would be useful to have
the correct name for further searching.

to be fair, I found my set of bits, but there's nothing exactly like
an inverse screw. There are 4 plain screwdriver bits with a
rectangular slot in the middle which are 4,5,6 and 6 mm diam.
Might do if the screws aren't too tight.
