I can't check cause mine getting repaired but maybe try a future screw, the are both 3/32 whit worth threads, not sure if they are longer.
Or...
If you get really stuck, drill and tap another screw hole on the other side to the screw that is already in there.
Or possibly...
I think there is a way to drill the plastic bit out and replace it aswell. Or you could go to a bolt shop and get a grub screw that is slightly larger thread than the current and try that or even just get a longer grub screw in the same size.
If none of those work.... Masturbating on a Cheese grater is probably a better way to spend your time....
