We just got a 1970 Holiday Traveler and we are fixing a few things because of water damage. As I am taking put some of the screws/bolts (not sure what they are called, small but with a bolt head and screw in with no nut) its into some solid wood, but the heads are rusted and rounded off or just deteriorated. I cant really pound on it because there's nothing stable to be effective and I don't want to damage the aluminum. I tried to pry it from the inside, but I'm afraid of damaging the aluminum and I cant get enough pressure to push or pull against. I dont have a picture but I can get one in a day or two if needed to make more sense. How can I get these screws out of the wood? Many came out because the wood was rotted, but there is a good section that I need to take off to replace the rest of a board. It's sort of weird that they heads are so rusted and look mangled, but the wood is still as solid as its secured solid. I did spray them with some sort of penetrating spray to get the rust to loosen, but not being able to grip the head, it really didnt help. Any suggestions on how to do this? I'm afraid to use heat, and a little hesitant with even a small grinder but would consider that if that's the only way to do it. Thanks in advance.
Hi there! Newbie here, but I am currently rebuilding a 1969 Holiday Vacationer, so I believe I am quite familiar with exactly what you’re talking about. Most of the screw heads along the trim in the midsection of my trailer were rusted like this. Some, I was able to remove with a screw extractor, which was only about $3 at the hardware store. You drill out a tiny hole in the screw (the extractor you buy will tell you exactly what size is compatible), then it’s a little reverse-threaded bit that will grab and back out the screw. This was incredibly time-consuming, and I wore out a bunch of drill bits.
Most of them, I took an angle grinder and cut the heads off. Being on top of two pieces of skin, and the trim rail, I was able to pull off the trim and skin, and then had just enough to grab with vice grip pliers to back them out.
But, whew. What a pain in the butt. I’ve also had a few break off while trying to remove, and I’m still trying to figure out what to do about those. Good luck!
Another way to remove these screws is to slot the head, then use a flat blade screw driver to remove. Sometimes the head will break off. Removing the rest of the screw is a pain. Usually, I just replace the wood so that the new screws have a place to grip.

Do what Vikx said. I used my die grinder with a cut off blade and slotted the head on the screws and then a flat head scew driver would take it right out. I also think the heat from the blade loosen the corrosion and helps break the bond and easier to remove the screws.
