Allgrip Drywall Boxed 3.5 x 50mm, Coarse Thread, Black, supplied in a pack of 1000.
Drywall screws have a bugle head that sits flush in plasterboard without tearing the paper face, and a sharp point for fast starting. Fine thread suits metal stud; coarse thread suits timber stud.
Drive with a drywall bit or collated screw gun so the head sits just below the surface.
