4.2 x 42mm Self-Drill PH2 Cement Board Screws (Box of 200)

Self-drilling cement board screws, specifically designed for fixing cement based boards, aka hardie backer board, onto steel dry-lining frames (max. 3.0mm). They feature countersinking ribs under the head to ensure a flush finish. The self-drilling point will easily drill through up to 3mm steel without the need to pre-drill, and the self-tapping thread gives a secure hold. These screws have an exterior grade coating (1500 hours salt spray tested) for superior corrosion resistance in damp or corrosive environments, when compared to standard fasteners.
