Black Phosphate Drywall Screws 4.2x65mm (Box 500)

These 4.2 x 65mm Drywall Screws have a Black Phosphate finish and come in a handy box of 500. They are designed specifically for drywall and are ideal for affixing fibreboard, insulation boards and plasterboard to steel or wooden studding.Constructed from fully hardened steel and coated with black phosphate, these screws boast a sharp piercing point and a thread that makes it simple to insert them quickly and securely with a strong grip. These screws also have a bugle head design, which allows them to be easily embedded into the dry lining without the need for countersinking. This prevents surface damage and produces a smooth finish.
