17mm socket on a 10mm bolt?

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?

SAE bolts aren't this confused.

makes sense to me. The wrench size is the distance across the flats, the nominal size of the bolt is related to the size of the threads. SAE works the exact same way. e.g. a 3/8-16 UNC bolt or cap screw typically requires a 9/16" wrench to tighten.

The only exception that I'm aware of is Whitworth, although I'm sure that someone will correct me with an even more obscure example.

They certainly are. What size socket do you use on a 1/4" bolt? The advantage of metric is you don't have 29/32 and other little used sizes.

Maybe you're right. Maybe I didnt' notice because SAE bolts are the right kind of bolts, and not these alien bolts they sent me today. Why can't they protect our border better?

Thanks.

...and even worse; the metric system!

16mm?

What, do you think that a 1/2" diameter SAE bolt has a head with flats that are 1/2" across?

Bzzzzzzzt. Thanks for playing, though.

There are two dimensions at work here:

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.

Whitworth AND BSF used thread size nomenclature for their wrenches instead of AF size

Except for such oddball sizes as 9mm.

11/16 is "close enough" to 17mm for most assemblies. A 17mm is just a tad too small for an 11/16" nut.

1/4" No?

No, but I think it takes a 1/2" wrench.

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.

Exactly.

Inches for defense, not one millymeter for tribute.

And to think that there was consideration of official adoption of the metric system back when Thomas Jefferson was President. How much simpler things would be if the chang was done then, before industrialization. The country was still in a rebellious mood when a national currency based on the decimal system was adopted, but by Jefferson's time had already turned conservative enough that a change to metric was defeated.

7/16"

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

Nope. Guess again. A 5/16 bolt uses a 1/2 inch wrench. A 3/8" bolt takes a 9/16" wrench. A 7/16 bolt takes a 5/8" wrench, and a 1/2 inch bolt takes an 11/16 inch wrench. 9/16 uses 3/4, just off the top of my head.

The issue with METRIC is there are several "standards" Japanese (JAS?) standard uses 10mm on 6mm bolts, 12mm on 8, and 14mm on 10 and 17mm on

10 American Metric uses 11mm on 6, 13mm on 8, 15mm on 10 and 18? on 10.

European stuff can be either, from what I remember.(ISO)

So how come my damn tin shed uses nuts and bolts that take an 11/32" wrench? Which NONE of my several sets of sockets or nutdrivers or box wrenches includes, and nobody in town sells onesies in oddball sizes? (except maybe Sears, who wants an arm and a leg for onesies, to make up for their deep-discount sets.)
