which screws do I need for window hinge

[movieman]

Hi guys here are my window hinges and they need to be reaplced as they have snapped. the problem is i dont want to use rivets (prefer screws) in case i need to change again.

Does anyone know what kind of screws or how I might measure the screws needed thanks

Screws to the depth of the hinge plus deep enough to fix into the first layer of plastic. Screwfix turbogold plus.

I would use self tapping screws (with wide/flange head):

Bare in mind there could be some steel reinforcing in there so you will most certainly need self drilling screws, self tapers fine if just going into plastic, hit steel and they just stop
