They are like a torx nut target than a torx bolt. Only a ring spanner or socket fits on them
is it like that on the other side as well?
That's being used in the wrong way.
It should sit in to a retainer the stop it turning then you turn the other end of the axle to tighten it insteaed of trying to turn the "nut"

Macadamia?
whatever it is, it shouldn't be there ...
Interesting, what does the other side look like? Has it got a through axle on a bike (DJ?) With horizontal dropouts?
You probably won't die but it's not as intended.
Was that a second hand purchase?
Looks like a ghetto through axle conversion! Somebody taking a grinder to the sliding dropouts and opened them up to 12mm, then used anything available to fit the axle.
Looks like alen key flats inside the end of the axle.
Mate picked up a cheap jump bike off FB. It's a through axle, I'm guessing 142x12 but haven't seen it in the metal yet.
Hopefully it hasn't been ground out too much. Or at the least it's still safe.
Still a couple of decent doubles and we'll find out!
Edit: thinking about it, it must be longer than 142 or the but wouldn't fit on the end.
142 is the spacing between the dropouts (135mm + 2x 3.5mm pockets in dropouts to locate the axle). The axle is always longer (obvs).
If the dropouts have been opened to 12mm as suggested above it could now be 135x12mm (an older 'standard').
Looks like a shimano e-thru bodge to me
I was expecting the "elephant sitting on your face" joke. Disappointed.
Disc rotor is also on backwards.
The plot thickens: it's a Superstar MTB hub with a bolt though hub, laced to a 26" rim (I would have expected 27.5 for the age) but either way it looks like someone has bodged round the needing a bolt-on axle with a bolt through. I'm intrigued to see how well the axle stays in place.
I don't remember seeing a bolt-on axle option for a Superstar hub
Disc rotor is also on backwards.
Yeah, get this changed too.

Jump bikes are often 26".
