The Self Drill Drywall Screws + Bit are only available in boxes of one thousand. These screws are available in numerous lengths; see our drop down menu for the full list. These screws are specifically designed to attach plasterboard to timber or metal studs. They have a super tough end which withstands more pressure. Their ‘self-screw’ end means that there is no need to drill pilot holes. They are also able to drill through thicker metal and timber with ease.
