Dry wall screws or plasterboard screws are excellent for fastening plasterboard to wood, these specially designed screws are Black phosphate coated to prevent rust, they are hardened and have a bugle shaped head which allows you to sink them into the plasterboard without tearing the paper covering.
Dry wall screws are extremely tough and can cope with the extreme amount of torque that is exerted by today's modern electronic screw drivers, never try to use stainless steel screws for holding plasterboard as they cannot stand the torque and it is likely that the head will shear off from the screw.
