That's not a factory takedown screw. The Ruger screw (12-24) has a narrow shaft, so it's captured when screwed into the escutcheon.

Maybe you have the wrong size screw and thread pitch.

the screw's threads look fine...but that's as to be expected

when it's a steel thread versus an aluminum thread, guess which one is more likely to come out on the losing end?

right, and the OP did say this was going on in a factory stock didn't he

so, this is going to take a bit more of a story now to know what's actually going on here

ETA: was the takedown screw already changed to a 1/4-20?

 

[combatinfidel]

Nothing has been changed should I get a 1/4-20 and tap the receiver?

I don't even see how that bolt is treading through the stock to even reach the action.

No, you need to get a factory bolt.

 

[combatinfidel]

Is the bolt supposed to thread through the stock or simply slide through

Too hard to guess the scale of the picture. Another theory would be that the screw is an M5 metric. An M5 metric would have an outside diameter of 0.1968". The inside diamter of a 12-24 screw hole is 0.19". Depending on the tolerences, that might feel like the screw is barely catching the threads?

That is exactly what it feels like

It screws into the escutcheon, and once it goes past the threads (to narrow section of a factory screw), it spins freely.

 

[crackedcornish]

show us the pics of the stock (including the escutcheon) and the takedown hole in the receiver..and tell us the story on where you got the rifle from, 'cause somebody along the line swapped out that takedown screw

once we know the whole story, then we can offer you some help on which way to go

if that receiver has already been modded to 1/4-20 and you stripped it, you will most likely be looking at helicoiling it

This is what the bolt looks like in all six of my 10/22s.

Or $4 or $5 on ebay.

I have tried pressing the escutcheon thinking the screw head was bottoming out on it and that didn't help putting the screw directly into the action there is something me play and it feels like the treads are not grabbing the threads in the receiver

They must have made some changes recently then. Curious, what stock is on this gun?

Then you might be able to contact Ruger and get them to send you a new screw for free, or send the gun in for repair.

 

[combatinfidel]

I'm going to order a new takedown screw and see what happens
