They would be 'drive screws', like these: [Linked Image]
They are installed by hammering them into an undersized pilot hole, so as you say, it's very difficult to get them out.
About the only way is to punch them out from the underside, but this only works if the pilot hole is drilled through.

They are hardened, so drilling them out is also difficult.
