Self-drilling hex head screw designed for fastening through AAC to top hats. A versatile all-rounder for steel construction, the coarse thread allows for faster installation compared to fine thread alternatives, improving efficiency on site.
The flanged hex head provides increased pull-out strength, while zinc and galvanised coating options make it suitable for both internal and external applications. Screw drills and taps its own thread—eliminating the need for pre-drilling and ensuring quick, reliable fixing.
