Self drilling hex head screw with a 5 series drill point (aka series 500) for drilling through up to 12mm mild steel in metal brackets, components, steel sections and assemblies. The flanged hex head lends to high pull-out strength. Available in both class 4 galvanised finish and stainless steel variants making them perfect for internal, external and high corrosion affected applications. ICCONS 5 series (series 500) self drilling hex head screw has a hardened steel 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).
