Zinc electroplated bugle head self drill drywall screws for fixing plasterboard to heavier gauge metal sections up to 2.5mm thick without pre-drilling. The self drill point cuts through steel quickly and cleanly, and the twin fine thread provides a strong, reliable hold. The 4.2 x 75mm size is well suited to thicker multi-layer board applications on heavier gauge steel framing. Supplied in a box of 500.
