EDIT: I believe I found the answer, it's something turned by this: https://ctatools.com/products/5065
Found some trash on the street that i'd like to take apart, but this screw is in my way.
It's like a hex bolt, but with 5 sides, and rounded (a bit like flower petals).
Here's another picture from the top:
I tried turning it with various tools (hard to get pliars in unfortunately), no success so far. The material is very soft, which doesn't help..

That is some variety or another of a “torx star” head. They vary in size and are listed as TS-10, TS-15, etc. your best bet would be searching torx star and buying a set of bits to try out various sizes.

And it's an inverted torx (with 5 points) as usually the screw driver is male and the screw head is female - I think that's the right nomanclature.

Oh ffs I didn’t notice it was inverted from the pics. Good catch. Someone really doesn’t want you to open that shit OP.

true, looking at second pic it's very hard to make out. I tried to capture it on the first picture, but it's not that good

I think I found it, it's this kind: https://ctatools.com/products/5065x12

yeah, it is inverted (or "external" torx according to your link). They also made sure to sink the screws into a whole where no pliars will fit...

Edit again: I was wrong. TIL about EPR Torx. Just search that and you should find the right set.

I can only find pictures of 6-lobed Gamebit screws

It's hard to tell from the pic, but while that may be epr torx, it also looks like a pentalobe.
thechadwick@lemmy.world · 3 pts · 2y
Hard to say without a scale reference, but if it's small, I very small might very will be a proprietary fastener for higher security applications. If it's a Tesla battery pack, then the epr 5-point torx is a good candidate. If it's an apple device then searching pentalobe might get you farther.
What on earth is it? Pics? Ruler next to it?

Torx is six-pointed.
BakedCatboy@lemmy.ml · 4 pts · 2y
Torx plus is 5 pointed, for example https://www.mcmaster.com/products/screwdrivers/drive-style~tamper-resistant-torx-plus/
