I'm removing some old speaker mounts from a wall (I believe the wall is plaster, but I'm not 100% sure. It's definitely not a drywall).
Two of the screws are stuck, and I'm at wits end trying to get them out. The screw doesn't budge in the slightest, no matter what I try. Things I have tried:
- Multiple screw bits/screwdrivers
- Steel wool/tape under screwdriver for more grip
- Applied WD-40 to screwed
- Irwin extractor kit -. I can't even drill into the screw with metal drill bits
- Locking pliers -. I can't get a good angle/grip
I'm not sure what to try next. The other screws removed easy enough - there's some rust/corosioncorrosion in the threads of the other screws, so I'm assuming these are extra stuck for the same reason, but I can't say for sure.
These are also a pain, because they are high on my wall -, so it's hard for me to really lean into them on the ladder and not worry I'm going to slip and fall.
Any other suggestions on howHow else can I to remove them?
