What's this type of screw head called?

Tamper proof hex or tamper proof torx respectively, drivers available(*) in sets from Maplin, CPC or a market stall near you.

Alternatively, insert a small screwdriver into the head, and twist. The pin will ping off (mind it doesn't go in your eye), and then a regular torx driver will work.

You make it sound sooooo easy ;-)

I recently had cause to undo some stainless M5 security torx bolts without access to regular tool. That pip turned out to be toughest SOB that cursed this earth. The heads finally succumbed to my angle grinder.

Totally OT but

The cells at my local police station use the 6 lobed variety to box in the radiators and make up what is supposedly called a bed. The rads are under the beds and the boxing in makes a platform for you to sleep on. They are also the same torx screws as used on Gent hand dryers.

Now how do you know that!!!!!!!!!

I have fitted a Gent drier or two.

And 17 hours in the cells is a little slow. I had read all the graffiti on the walls and there was not much else left to do but nose around.

"Everything" succumbs to an angle grinder :)

The trick was ensuring that the PC they were securing didn't succumb too ;-)

In a slow moment I thought that it was a luxury nick, wot with having hand driers in the cells . . . . and that's with me remembering the whole story as previously recounted.
