anti-tamper screws like torx

I am trying to find the name of an anti-tamper screw that (so that I can source the appropriate tool). It looks like a torx (star shaped) (6 pointed I think) but has a pin in the middle so the tool will need a corresponding whole in the middle. I think it is around 8mm across. The pin is about 1.5mm.

Anyone know what its called?

I thought they were just called "torx security bits" - somewhere at work we have a set like this

http://www.drapertools-online.com/b2...pp_skmno=78276

which has the whole lot both male and female, and the security bits. Bit pricey though - however there are cheaper options from Draper if you look on the same site.

Of course the other alternative is a small chisel to "modify" the security bit in the middle

thanks Stephen - google seems to agree with you - I thought all Torx bits were intended for security/anti-tamper but it seems I am wrong and they were invented to make the car assembly process easier rather than the dissasembly process harder!

thanks - If it was my property it would have been drilled out already but I don't really want a charge for criminal damage.

Maplin sell a pack of bits which fit most of the anti-tamper screws. I think you get 20 pieces for about 8. They're the 1/4" hex shank type.

I can think of a few more if you don't have the right tool available..............
