Probably had one or two screws hard to remove when removing the rear baggage bulkhead panel but today for my condition inspection (annual) seven refused to back out. I don't think it's the driver as it takes a tremendous torque before the Philips head gives out. I drilled one and hope to sneak past the bulkhead (remaining screws are up high) and catch the tails to start them this afternoon. Been removing these screws since 2017. Same hangar same temperature. All I know I have to do something once I re-install the bulkhead. I'm not sure if it's the threads in the plate nuts or the contact on the painted bulkhead? Might try Boelube on each screw and a nylon washer on each head.
So much for a ten minute job.
