What tool to remove this aerospace bolt?

As per the title.

Looks like a standard 12 point socket is all that’s needed?

12 Point self locking nut, most probably Imperial if on an aircraft. Use a 12 point socket/wrench as a poster above said.

Also called Bi-hex.

Good excuse to buy a set of 12-point hex sockets anyway - when working at arms reach/ in difficult space, they give you more leeway in terms of being able to shift the thing in just 30dgree increments if you have to, not a full 'flat' being 60degs...

Ok cheers, slight embarrassing post......

Got 12s just not that small, shops it is.

Probably a deep 3/8” drive socket from Halfords will be perfect.
