thank you for the fast reply and adviseScrewdriver buddy, you're going to have to hammer it in and use it to extract the ram cap... Or you can use a bigger size Allen key or socket, but it'll have to be hammered in.
Unless you have a screw extracter bit, but whatever you do to get it out, you'll need a new one.
Tash has some in his sales thread of creed/demon spares.
