Loose Metal Screw/Bolt Tip - A couple of years ago I had to repair an aluminum fry pan my wife just wont throw away, the handle had come loose and I could fit it with a bigger bolt, or mash the hole to make it grip better. So, I thought about the toothpick and wood fix, and tried the same type of fix to the bolt. What I did was to wrap the bolt with aluminum foil so that it would not unravel when screwed into place, it worked like a charm, and it is still holding up. I have used this repair on many things since, and it's really quite handy for repairing aluminum and tin products as much of nothing else applies here. I've even used it on a screw that holds a scope to a rifle, it's been a year since that repair, and probably a hundred rounds of .762x54 have gone down the barrel of that M44 Mosin Nagant with the scope holding tight and true.
