triangular security screws

[Fred]

Hi,

I wanted to dismantle a broken kitchen appliance but found that the screws needed a triangular shaped bit. I have never seen these before. I have found some screwdrivers on Amazon:

was confused by the "Tnumber" classification, as I associate that with torx bits. I presume the number is the length of one of the sides of the triangle in millimetres.

Does anyone know more about these screws? Do they have a name?

TIA

Trust you, geoff!

How did you move those, then?

I created my own (ooh missus) tool

drilled a centre hole, put a bevel on it with a larger drill bit then,with artistry that drivel could only dream of with a hacksaw, cut the fingers to fit the slots

Still got it somewhere - not the most beautiful bit of art on the planet, but it works

Very common on kids toys here in the US. I don't have a driver for them, but if they're screwed into plastic I normally manage to undo them with a flat-bladed screwdriver of suitable width, then replace them with screws from the spares bucket that have a more useful head.
