Self tapping nuts in door.

[Jasper]

Another day, another assembly headache. I’m assembling the doors and the screws for the armrest don’t fit the welded on nuts in the door anymore.
How do I advance from here? I know the E3 used plastic/nylon nuts that fit the square hole. Do I remove the welded nuts and substitute with the red ones? Or another kind? Or do I jimmy the nuts somehow so they can grab the screw again?

Are there actual nuts? I thought there are threads intrinsic to the door sheet metal. You can use rivet nuts. You can rig up a system to install them without buying a rivet gun.

What dose means dose not fit anymore?
Is the screw too big or too small?
To small, tap with a hammer on the welded nut from backside to get the hole smaller.
To big, wrong screw picked.

The holes - some of them - are bigger than the correct screws. And worn to a degree that flattening isn’t really an option anymore. Perhaps someone before me replaced them with the E3 plastic nuts or something completely different.
Or rivit nuts. They’ll work.

I had the same dilemma.
In my case, the original screws didn't catch the sheet metal thread thingy welded into the door.

I replaced them all with M5 and M6 weldnuts

Erik, that has to be the gold standard. Well done. I ended up squashing the threads with a 4mm bolt, nut and a handful of odd washers. It worked well on the three threads that couldn’t hold a screw. Crisis averted for now. Next time they act up, the threaded plates will be removed and replaced with red clips or caged nuts.
