Help: triangle security bit wanted

Hi all,
I need to open a domestic fan casing which is is screwed in using screws
with heads having triangular recesses, similar to the one in the picture
below:

Any idea where I can get a screwdriver or bit to fit these screws? The
commonly available sets from Jaycar and Dick Smith don't appear to contain
this type of bit.
Cheers,
Rab (rarsin at hotmail dot com)

Re: Help: triangle security bit wanted

I had the need to open quite a few items with these screws a year or so
ago, and I couldn't find a suitable bit anywhere. So, I made one.
All you need to do is get a hex bit of the right size, and file off
three of the points. Voila - triangle bit.
My "prototype" worked so well that it's still in use now, even after
removing and replacing hundreds and hundreds of screws, using an
electric driver.

Re: Help: triangle security bit wanted (NOT tri-wing)

Guys, I need a triangle bit, not a tri-wing bit. The sets sold by Jaycar
and DSE contain tri-wing bits, which look like this:

The tri-wing bit is tapered like a Philips bit, but has three "wings"
instead of four like the Philips bit. I need a bit with a triangular
cross-section and parallel sides (not tapered).
