need a filler as Miracle Glue will not fill a gap on its own. Use
baking soda, talcum powder, sawdust or even cinnamon or coffee to
match a colour. I find sawdust in this case is the best as
it has a bit of give.
Build the sawdust up in layers with the glue - a quarter
inch at a time. Let it cure and then tap a hole for the screw
and away you go.
