We are going to need more info as to the type of hub and threading type (if you know or its indicated) and the freewheel brand and any markings on the back especially if it is a Regina.

How far on did you screw it? I would take it off and thread it back on and see how it holds up.

If you can remove it, you might be able to clean up the buggered threads a bit with a triangular jeweler's file. Enough to get it threaded properly, perhaps.

I hate to admit, but I did this recently. Use your freewheel removal tool and a solid bench vise to remove the freewheel slowly. If you're lucky, the threads won't be (too) buggered, and a bit of careful work with a tiny file (the triangular jeweler's type is, indeed, perfect). I was lucky and very little file work was required.
Then check the freewheel threads. In my case, I went with a new freewheel.
Good luck!

Yes, are you trying perchance to thread an Italian freewheel onto an ISO hub, or vice-versa?

Don't feel bad. This mistake is easy to make, because the diameter-to-thread-pitch ratio is so big. In cases like that, I often screw it on backwards and wait for it to "click" before screwing forwards. That gives me a clue as to whether it's straight.
If you're over 40 years old, you may need a jewelers loupe. I have one in my workshop.

^ this. Starting the thread on fasteners backwards and waiting for the click is a really good trick and one I have used for years to ensure you are not crossthreading. +1 on magnification... I have a pair of the highest power Optivisors which I use both for bike work and electronics work.

BTW, 126s are for 6 and 7 speeds. 5 speed freewheels were for 120 mm hubs.

The threading is the same, other than the ISO/Italian threading issue. Italian threaded freewheels/hubs should be pretty rare.
See https://sheldonbrown.com/freewheels.html
For the 5 speed freewheel on a 126 hub, you might want a washer or spacer behind the freewheel for spacing to get chainline better. No idea if LBS' have these around anymore.
Do you have the correct freewheel remover for this freewheel? If so, I would do as many here have advised and remove the freewheel and take a close look at the threads. Your LBS will probably want to sell you a new bike cuz they can't get a threaded hub, yada yada

Wow, that's cool. I think I've seen these but didn't know what they were.

I was just going to post a pic of one of those. I have used them with great success on wheel studs (auto).
There was a need for one this week and I didnt have one but somehow or other I found one at a flea market. Talk about a needle in a haystack.

I did the same thing and took it to my LBS and he placed the freewheel in a vice and held the wheel. The large diameter allowed a better feel for how level the wheel was while threading it on.

Still cant get how it can go fine at the beginning and then the user assumes it went to hell later on. When you screw that half way in pretty much there is no way to thread it wrong afterwards. If you put an ISO freewheel in an Italian threaded hub (or backwards) it will feel tight at the end but it will thread just fine as long as you dont change the the freewheel every single week like for year.
Had to google the word kilter because i did not know what it was. The freewheel actually changed the angle or something? if not then you should be ok but the only way to know is to take the freewheel out. Do not harm to ask this questions ok? You just say what happened (lightly described) but no details about anything... so we can only assume things.
1 did you clean the threads before putting the new freewheel?
2 Did you grease the threads really well?
3 are you sure the hub and the freewheel threads were compatable? there is italian, english/bsa and who knows what else moving around. Regina made them all. You can mix iso, bsa and italian. But well you can have something else in there.
4 what brand of hub are you talking about??
5 the freewheel actually changed the angle half way in? never seen such a thing ever...
6 the freeewheel just got tight half way in or something?
7 good luck

Or are you referring to "wobble" when the freewheel rotates on its hub? If so, this is normal.

Once you get the FW off and clean up the threads, I would take a bottom bracket lockring, oil the hub threads, and screw the lockring on and off a few times to make sure the threads are good. Then grease the threads well and carefully thread the FW on by hand only. If it starts to bind, use the removal tool right away to remove it, and start over.
