I'm getting into the specialty items now. So I'm gonna start showing you some special nuts.
This is what they call a left-hand jam nut. You can see that it's a low profile.
Okay. The only way you can tell it's a left-hand nut is that it has an arrow right there.
And that arrow shows it turning to the left.
That's the only way you're gonna know when you have a left-hand nut. You got to look for that arrow.
If that arrow exists, then that's a left-hand nut.
This is a reducer nut.
So you can see on one side it has 3/8"-16 and this side has 1/2"-13.
If you had some threaded rod and you wanted to reduce it down to a smaller size or the opposite
where you want it to go from 1/2"-13 to 3/8"-16 you'd use this reducer coupling nut, as they call it.
That's the way that that would work there.
This is a standard coupling nut. They come in various sizes and lengths.
Different thread pitches: fine or coarse thread.
All these different items I'm showing you do come in coarse and fine thread.
This is a knurled nut.
Commonly used in chandeliers, tattoo machines, many, different types of finished applications these are used in.
These are the type of things you put on with your thumbs. Don't usually use a wrench on this type of a nut.
That's the same thing with a wing nut. Wingnuts are always used with thumbs.
No wrenches involved in these nuts.
Next, I have cap nuts. So you have low profile, high crown, and then we have two tall.
We have two tall in a flat head, and we have two tall in a rounded head.
Now the two tall come fully threaded all the way to the inside; to the top.
They have full threads all the way through. You have on the two tall, what they call a flat top.
So you can see the top is flat and it has a chamfered edge around it.
The round top is just rounded over like the standard cap nut at the top.
They call these two tall because they're approximately, if you took the high crowns, double the height. Almost.
If you had two high crowns, that I don't have here but if I did, it would be close to the size.
That's why they call it a two tall.
I have here what they call a T nut. T nuts are used mostly in wood. That's most common. They do use it in plastic also.
T nuts are made to go in the holes that were drilled into the wood or into a plastic product.
Then these prongs that you see here, they come in three-prong, four-prong, this particular one has four prongs.
One, two, three, four. Four prongs.
Then it has this barrel. They call this a barrel.
You push it into the hole that you drilled and then you suck the screw in and this flattens out with the wood.
Typically. Very commonly used nut.
A castle nut. These are typically used in cars. You'll find them on axles where they hold on wheels and bearings.
We're going to drill out a bolt, slide the cotter pin in, to show you how this is locked in place.
