Anybody know what the hell these anti-tamper heads are called

Go to harbor fail and look through their tamper-proof sets. There is a pretty decent selection, but I haven't seen this exact one before. Good luck

If all else fails you could measure the circles and their offset with a digital micrometer and have a machinist make you a bit.

The whole point of these heads are that they are annoying as fuck to buy, and you probably won't be able to tag a name to them.
If you take it to a hardware store and they can't tell you shit, either call a machinist or drill 'em out.
You sure the previous site manager wasn't just being a bitch, or were security heads specified?

Dremel and a flat head. Then use what you want.

Nice try Trayvonisha...

>we dont have access to a machine shop
>we dont have a drill

if im going to be brutally honest, i'd say that is probably a screw cap. not actually attached to the screw itself. try levering it up by sticking something in the hole.
such a design in a screw head would damage the threads making the screw unsuitable for anything important because the torque would be applied at an angle.

take a dremal and slot the fuckers?
