Self-drilling hex head screw with fine thread for fastening through mild steel in metal brackets, components, steel sections and assemblies. This screw is an all-rounder with countless applications in the steel construction field, however the fine thread lends itself to a slightly slower install which enable the installer to adjust to the screw with greater precision more so than the coarse thread counterpart ideal for thick steel. The flanged hex head lends to high pull-out strength and available in both zinc and galvanised coating making them perfect for internal and external applications. ICCONS self drilling hex head screw has a hardened steel point (tek point), and fine thread enabling the screw to drill and tap its own thread, without the need to pre-drill (please see screw self drilling capacities).
