Having Problems removing 1.5 hex screws from camera

Having Problems removing 1.5 hex screws from camera to install camera lens filter kit , tried 3 different 1.5 hex allen keys no avail , the allen key came supplied was crap , those screws are really tight .
Might have to drill carefully and try to use pliers to remove post screws , any ideas before I do this .

The post screws are the screwdriver which came with the phantom, the hex is for the grub screws at the back to hold it in place.

Apologies they are hex, I got mine out okay with the supplied hex but used the short end.
