Don’t order hex nuts from Amazon Login/Join

I ordered five 9/16” steel hex nuts from Amazon. I wanted four for spacers to set 9/16” plate separation of my Breville Smart Grill – didn’t care about thread size.

I received five 7/8” steel hex nuts. Oh well, mistakes happen. Low cost, not worth my time to return ‘em. Ordered five more 9/16” steel hex nuts (from a different Amazon supplier). Received five 7/8” steel hex nuts again. Damn.

OK, ordered five 9/16” brass hex nuts from a third Amazon supplier. Figured that with the more expensive brass nuts they’d be more careful with the order. Received five 7/8” brass hex nuts. WTF?!

I’ve finally learned my lesson. I’ll drive the five miles to Marshall’s Industrial Hardware to get my four hex nuts. Anyway, it’s a fascinating store – I seldom leave with nothing but my intended purchase.



Look about you.

I love Marshall’s! My co-Grandpa told me about it, he works on cars all the time.
They also have a great tool selection with lots of overpriced German screwdrivers and the like.
Most recent purchase was strut channel hardware.
For those not in the SD area, here is their website:
Marshall’s Industrial Hardware

Do you have a link to your purchases? I've never seen a listing where the hex nuts were listed/sized by thickness of the material/size of wrench or socket needed.While not super common 9/16-12 thread pitch nuts would have a fairly substantial size like 7/8" to 1". I don't have any handy to measure to accurately give dimensions.



I'd rather be armed and unharmed than unarmed and harmed.

It's not Amazon. A 9/16 thread typically uses a 7/8 hex head. If you are looking for a 9/16 head buy 3/8 nuts.

I don’t understand that at all. But I’ll take my Mitutoyo vernier caliper along when I go to Marshall’s to be sure that I get hex nuts that are 9/16” across the flats.

And yes, I know that a 9/16” nut is actually slightly less, and a 9/16” socket is slightly more.

Nuts are sized by the thread size (the hole) not the outside of the flats. Is that the confusion here, or am I the one who's puzzled?

No Artie, I believe you are on the right page. In my lifetime(51) we've always bought hex nuts based upon the internal thread size. I'm believing the OP has a different barometer to measure from. That is why I was hoping for a link to the product to confirm suspicions.

I'm not puzzled at all. Everybody knows you can't size up the hex nuts until after they've seen the witch doctor.

They sent you exactly what you ordered. Maybe not what you wanted, but they did send what you ordered.

Nuts are "sized" by the I.D. of the hole, not by the outside measurement.

The light finally dawns. Son of a gun – my whole life, I thought a 9/16” wrench would fit a 9/16” nut. Silly me. I thank the forum for educating me.

And my apologies to Amazon, too.

As shiftvtec said, 3/8" nuts (ID) measure 9/16" across the outside flat edges; i.e. you use a 9/16" open end wrench for that size nut.

Just to save the OP some possible trouble in the future, it's not just nuts.

Pretty much all threaded fasteners are sized this way.

The numbers in the name describe the asme thread size and pitch. Rarely ever is the size of the tool needed to operate the fastener mentioned.

For example a 1/2 - 13 bolt has a threaded shank that is 1/2 inch nominal diameter and a thread pitch of 13 threads per inch. A 1/2 - 13 nut will have a threaded hole that fits a screw with a 1/2-13 thread.

Metric is done the same except for the thread pitch. An m14x1.5 screw will have a nominal major diameter of 14mm, an measure 1.5mm between any two threads.

A 13 pitch screw will measure .0769" between any 2 threads, or 1/13 of an inch.

This knowledge is how a machinist or gunsmith can make a brake or flash hider that hits the correct torque value at the correct position to be timed correctly.

If i want to torque a muzzle brake to 35ft lbs, then test torque a brake and find that it takes 5° of rotation to go from finger tight to, say, 35 ft lbs, I can calculate how much to face off the back of the brake, so the it hits 35 ft lbs at the correct orientation.

A 13 pitch threaded nut, or muzzle brake will move .00107 inches in 5° of rotation.

Why in the hell would you buy 5 hex nuts from amazon? Are you bed ridden?

You're in San Diego, sure its been a few years since I was stationed there but all the Home Depots can't have closed already.

Nearest Home Depot: ~5 miles.
Nearest Ace Hardware: ~5 miles.
Marshall’s: ~5 miles.
Front door: .~20 steps.

No time pressure, the cost difference is trivial to me, and I have other demands on my time.

Wise up.

We all live and learn.



"It did not really matter what we expected from life, but rather what life expected from us. We needed to stop asking about the meaning of life, and instead to think of ourselves as those who were being questioned by life – daily and hourly. Our answer must consist not in talk and meditation, but in right action and in right conduct. Life ultimately means taking the responsibility to find the right answer to its problems and to fulfill the tasks which it constantly sets for each individual."

JIS is an exception. Take an M8 JIS bolt and you use a 12mm wrench. Buy the same nut from McMaster-Carr and it's a 13mm wrench (ANSI).
