I finally bought the trailer hitch for my Solara and it came with
M10 -1.25 x 30mm bolts. So how come I need to use the 17mm socket
on a 10mm bolt?



There are two dimensions at work he
1) the bolt shaft, and
2) the bolt head.

The "10mm" refers to the diameter of the /shaft/ of the bolt.

The "17mm" refers to the flat-to-flat dimension of /head/ of the bolt.

You're a Communist, aren't you. Your explanation sounds
reasonsable, just like one a Communist would use.

And you sound helpful, just like a Communiist would be, until you
trust him.

But I'm not going to fall for that.

Maybe you're a Socialist. Everything I said about Communists applies
to them too.

I apologize. That answer was intended for someone else, who had said
when I turned 65, I'd be eligible for Social Security.
