Default Loose tuning machines

Has anyone else seen this? Martin D-18S, slot-head, bought in 1972. I was changing strings today and while turning the winder saw the side-mounted Grover machine lift up slightly. When I tightened the screw that had come out, it didn't tighten completely. Checking others, I found some tight and some that also seemed to be stripped (hole in the headstock enlarged?). Is this unusual? Is there an easy cure? I did e-mail Martin to find out about warranty issues.

Very easy cure.
Remove the screw and cut down a wooden tooth pick to fit in the hole.
Re-fit.

Tooth pick works well.

Glue in the toothpick, drill the proper size pilot hole for the screw.

Rub the screw with a little beeswax, reinstall the screw.

I did add a small smear of glue but I didn't even re-drill the hole - the toothpick is very soft wood and the screw was happy to start threading itself and just having that little extra timber in the hole was enough to give it bite.

The beeswax is a good idea though.

I’ve used matchsticks successfully. Toothpick probably the better option though.

Sounds like a common enough problem...from using a string winder?
