Amazing quality reverse drywall screws for an amazing price here at Fix Factory. Designed for fixing low and medium density board to timber and light guage partitions. Typical use would be for fixing plasterboard to ceilings and stud partitions. They have a sharp point for drilling up to 1.0mm mild steel and a head design that avoids tearing the board surface. The reverse thread helps compress the plasterboard material to minimise debris escape and countersinking.
