JB weld is a 2 part metal and hardener, like epoxy. You can get it anywhere, auto parts, wally world, grocery store.... You put it in the original hole. Wait the cure time 20min to a few hours pending what type you get. Then you drill out the hole a little smaller than the threads, then you put the screw in. Presto!! I always keep JB weld in the truck in my trail kit. Wonderful stuff.
