Rounded over external torx bolt

[RonD]

Looks to be an alien artifact of some kind, doesn't look like my EARTH made open end or box end wrench would fit that head, SAE or metric
So must not be made on EARTH

Does this help you old people...

No. I already blew up the original to that size.

I see an internal torx head bolt with chain damage to the smooth outside and not damage to the actual drive boss.

It's one of those optical collusional thingies. I can see it the way you see it. But because of the description given, I first saw it as an external torx (washer head) with one side ground away.

Like I said ALIEN, not of earth origin, asymmetrical alignment

Effing aliens...

Dynamite will solve the problem.

I've dealt with these before, but never on earth.

An internal torx wouldn’t cast a shadow...

Weld a nut on it and take it out.
