The screws I use for plastics look a lot like sheet metal screws but the threads are subtly different. You can search Amazon for screws for plastic to see.

Some of the screws are self tapping so they go nicely into a drilled hole.

I get most of my screws for plastics by disassembling things made of plastic before throwing them away.

Sheet metal screws will also usually work in many plastics if you are careful in sizing the pilot hole. Some plastics can be brittle. I'd cut a tapping slot or two in the end with a metal-cutting disk on a Dremel. (sometimes I do this with a small triangular file.)

What kind of plastic and what is the application? I built something from Lexan yesterday (polycarbonate) but I decided to use glue instead of screws.
