Sorry, shim or wedge of wood to help fill the hole. Along the lines of a fat toothpick. I fitted quite a few old doors and hinges that failed. The mounting was already mortised in place. I never found a filler that could hold the thread of the original screws until I put in a small shim/wedge/splinter in for bite. Too big a piece (and you would think bigger the better) and the old screw would not take as well. If really stripped 2 smaller pieces. For the boat I use some teak I have around and whittle off a piece. Oak would do well. Use a hardwood. You can dry fit with the screw before the epoxy.
