Three bolt kitchen drain strainer question

Hi All,
My kitchen drain strainer is rusting out under the sink. So it is time to replace it.
The thing uses a three bolt attachment, sort of looks like this:

I have see replacement drain strainer instructions on youtube and such, but not three both. Just a bug metal nuts to go over the bottom on the strainer.
Questions:
1) can I get a replacement in all stainless steel? Nuts and all?
2) is there some advantage to a three bolt configurations?
Many thanks, -T

The strainer is the removeable basket or metal plate with holes in it that comes out easily for cleaning by lifting and is not Under the sink. If it's really under the sink you must mean something other than strainer, like bracket or connector.

This one is meant for a garbage disposal. You can tell that because the 3 bolts are distinctive, and more so because of the small notch at 1:30 on the clock in the bottom hole. That indicates that the bottom hole is helical, to accept one thread of the garbage disposal (which only had to turn 40 degrees more or less to lock into place.)
Since 90%+ of American garbage disposals are made by InSinkerator, it shouldn't be so hard to find the one in this picture. I have one you can have, left over from when I installed a replacement GD but had no need to replace this connector, and I suppose many people have one since they come with the new GD. Ask on a Free Cycle list or even on Craig's list, though there's no reason to think the next one will be made of different material than the current one. Still, I think it's rare that they rust out and maybe the next one won't?

They sell a more expensive model of the GD in what they call stainless steel. I don't know how many more parts are SS or if the bracket is, but I'd contact InSinkerator and ask them.

It doesn't wobble. Same advantage as 3 legs on a camera tripod.

This is not the same as your first picture. One would think they both use the same size hole in the sink.

I agree. The 3 bolt is for installing a disposal but they usually give you a ring so you can just use the drain.

Did the Kenmore have the 3 long bolts like in the first picture. That's how I've been telling them apart except I've never had any that were different.
BTW, when I said, in a post that will probably be seen AFTER this one, that 90%+ are made by InSinkerator, I didn't mean that the all had that brandname. Hmmm. When I needed a replacemment, I might even have looked at the ones at Sears. Maybe if I'd opened the box I would have seen a difference, but I didn't look.
InSinkerator is unlikely to change its bracket because one of the big features is that they go in and out so quickly, and new ones fit the same bracket so that just makes it a lot quicker.
It's hard to reach under the sink and attach the heavy thing if it can't be done quickly, and I guess I kept missing the right spot, so it was so hard that what I've done is to take a miniature (well, small. Big enough for a car, but the base is only 16" long or so. The red one with the yellow? plastic handle. ) floor jack and put it under the sink and rest the GD on it and jack it up to reach the bracket. No need to rush.

You mean the rubber part? Yes, I kept the same rubber part too, and the new one is in the plumbing box in the basement if I ever need it. Of course I'm so truly perfect I never had anything drop into the drain that had to be removed so the old one was good as new.
Hmmm, OP, the second drawing does seem to call the bracket a strainer, but that must be their vague labeling, confusion, or some surprising standard usage in the industry. I think it's the first two, and strainer flange there means a flange that surrounds the strainer, which has already been removed by being lifted out for cleaning.

I was just trying to show the three bolts. This *is not* my garbage disposal.
What I was after was why the three bolts when every replacement I come across doesn't have these bolts anymore.
Okay now I have been looking at the "all brass" Jaclo 2804-PCH http://jaclo.com/products/detail?pid 3
But it does not use the three blot attachment. Any words of wisdom.
I am after trouble free (no rust) for the rest of my life, which, God willing, will be another 30 years.

Jaclo tells me to use the 2806 as it is better for shallow sinks, like my stainless steel sink:

This is all brass and American made. Any thoughts on stainless versus brass?

Yes. "He who flies by night will not see the daytime."
But back to the garbage disposal, the picture above is just called a strainer, or maybe it's a strainer that connects to a drain pipie, but it makes no reference to a garbage dispolsal. It's not the bracket that attaches to the sink and allows the GD to be attached to it.

I don't know. I've been here 33 years and i have no rust now, with a stainless steel sink and a standard connector like the link I provide above. What are you putting in the drain water? --------

Wnat does Jaclo tell you about GD's. This product also doesn't mention using one. If it were meant for that, you'd think it would. Do you have a GD?
You know, it's called a Duo strainer, so maybe it's for the side of the sink with no garbage disposal.
Amazon has a lot of these for sale but none have questions and answers or reviews, so I didnt' learn anything. I would call them and ask them if it fits a GD before I bought one, but if she says yes, I wouldn't count on it being true.

Are you teasing me? This is not my garbage disposal. That is the other side of the sink and it is not leaking.
