Self drilling Hex Coarse thread class4

Self-drilling hex head screw 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 coarse thread has a slightly faster install than its fine thread counterpart leading it to have fast installation characteristics. The flanged hex head lends to high pull-out strength and is available in both zinc and galvanised coating making them perfect for internal and external applications. Self drilling hex head screw has a hardened steel point (tek point), and coarse thread enabling the screw to drill and tap its own thread, without the need to pre-drill (please see screw self-drilling capacities).
