ASTM A193 Scope
Originally approved in 1936, this specification is heavily utilized in petroleum and chemical construction applications. The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature or high pressure service. This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material is often available in national coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8 threads per inch (tpi) for diameters above one inch.
Below is a basic summary of a few of the common grades. ASTM A193 covers a number of other standard specifications not covered in this description including B5, B6, and B16.

TRANCRIPT
Get ‘er done with Ronnie. Today, we’re going to talk about these things called “tools”. Now, “tools” have many different meanings. But what I’m going to teach you today is something that you would find in a hardware store. These are things to help you if something is broken or if you need to build something. If you want to build something in your house, if you want to tear down a wall and put up a new wall — maybe you just want to change the color of your room. Maybe you just want to paint your room. So I’m going to help you go through some vocabulary about tools. I can’t resist the drill sound. It’s like going to the dentist. This is not the dentist.
So as I told you — at the beginning of this, I said, “Get ‘er done”. Why is Ronnie speaking in a strange Alabamian accent from America? It’s a joke. “Get ‘er done” is an expression that people use to mean, “Go do something. Do it well. Get ‘er done.” It sounds very American, so yay. “Get ‘er done.” We’ve picked it up in Canada. Maybe you will hear people say it when they’re drinking. “Get ‘er done!” I don’t know. We’re crazy here, all of us.
The most common kind of tool that people use will be something like this. This is a hammer. It makes that kind of noise. This is actually a rubber mallet, but Ronnie doesn’t have a lot of supplies. She makes do with what she has. So a “rubber mallet” or “hammer” is for something like a nail. So a “nail” looks like this. And what you do is you — you hammer the nail into something. Be careful you don’t hammer your thumb. I’ve done this before. Hammering the thumb is very painful. “Hammer” is a noun and also a verb. Okay? So I can say, “I hammer in the nails.” So I take my hammer, and I smash the nails into my wrist. Not a good idea. Please be careful when you’re using these things. They just might bonk you in the head.
The next one we have is — it’s not a drink of vodka and orange juice, unfortunately, ladies and gentlemen. It is a “screwdriver”. Now, my screwdriver was very expensive. I did get it from the dollar store, which is another place where you can get these tools. Each screwdriver has a different head. Okay. So unfortunately, I do not know the names of the different heads of the screwdriver. I do know that this one is called a “flat” head because it’s flat. And I do believe that the one that looks like a star is called a “Phillips”, but don’t quote me on that because I just kind of guess and hope that they fit in. And if all else fails, just hammer it in. That’s the thing. So with a screwdriver, what you’re going to do is you’re going to take this thing called a “screw” — that also means something different. So you’re going to screw in the screw with a screwdriver. English is so repetitive. Okay. So one more time. So you’re going to screw in the screw with a screwdriver. This one you’ve to twist a lot. It hurts your wrist. If you screw too much, you can hurt your wrist and do other things.
The next one we have is a “wrench”. A “wrench” could look like this. This is a very big example of a wrench. I also have a tiny wrench. So this part, what’s going to happen is you’re going to take something like this. Now, this, I believe, is called a “bolt”. Okay? So we have these things called “nuts” and “bolts” — I know what you’re thinking about “nuts”. Not those kind. “Nuts” are something that go around the bolt, and they position the nut and the bolt so it doesn’t move. So what’s going to happen is I’m going to use my wrench, and I’m going to put the bolt — or screw the bolt into the wall. Or I can unscrew the bolt, and I can take it out. If you have a bicycle — I have a bicycle. I love my bicycle. Sometimes, you need to do repairs on your bicycle. Sometimes, you can use a wrench. Also with the other end of the wrench, there’s a “hacksaw” — not a “hacksaw”. I’m sorry. A “hex”. And you can crank it and take it off.
One thing that would’ve been useful a couple of weeks ago when my friend’s chain fell off and we had to change a tire would’ve been one of these. This is called an “Allen key” or “hex key”. So it basically fits in the point of something and turns it. So if you have a bicycle, this is a very important tool. Ronnie needs to bring this with her every day because Ronnie’s a bit of a klutz. That means she breaks things a lot. So an Allen key will help you undo things.
