Tamper proof Triangle socket

[Dave Liquorice]

I've got light fitting that has the cover retained by some tamper proof screws. The heads have a raised equilateral triangle with each side 4 or

5mm long. This obviously needs a triangle shaped socket driver, can I find one? Can I heck. That's looking on CPC and RS sites. The "security" bit sets don't have this particular type of bit in them.

Any clues? TIA.

Do you have any small hex sockets? A small enough socket will fit - but it'll need to be 3mm/4mm

Any chance of a pic, we could come up with an idea?

Is there any room to clamp a dremmel type chuck over it? as the chuck is basically a triangle jaw shape.

It occurs to me that the appropriate sized hex socket bit may work.

Dunno how big the triang is but... :-)

the tri socket on it.

I'll take some hex sockets next time I'm down there and my camera... Trouble they are also recessed down a fairly narrow hole in plastic, anything over about 3/8" dia isn't going to reach them.

I got a box of security bits from Aldi recently. 104 different ones I think, for 5 or 6 quid. Quality was not the best, but how often do you need one of those obsure shares/sizes? Worth keeping an eye out for future reference.

We use a 'Nutspinner' which has a long thin shaft and is gently forced onto the tri-head. IIRC it is a 4BA and a hammer ;) or a cheap n'n cr4ppy box spanner
