Since you don't need to give a warranty and only plan to play it yourself, there are a few DIY options.
You can use thread locker. Strong is probably best but also hardest to remove and would require significant heat. Usually not a problem but if it's close to a pad you might melt the glue or even burn the pad if you ever want to remove it. If upi thread it on now and it doesn't pull out easily or at all then this could be a good and the simplest option (if it doesn't pull at all I would consider medium thread locker).
As already suggested, you can use a sligthly larger screw and sort of let it half self thread half jam in there. I woul also grind two or three very thin channels lengthwise to shape the screw more like a tap, this makes it cut much better.
Does the screw hold with the spring off i.e. on those bottom threads it can't reach with the spring on? If it does, you can grind/file a bit off the key right where the hole is, to allow the screw to reach lower with the spring on (if you don't mind doing that).
If the length of the spring isn't critical, you can make a new threaded hole next to the original to avoid the soldering and possibly other work you can't do. Make sure it's not too close so there's enough thickness to support the threads.
