Choose zirconia ceramic hex head metric screws for assemblies that need an electrically insulating fastener with resistance to wear and corrosion. Zirconium oxide (ZrO₂) offers high strength and fracture toughness compared with many conventional ceramics, making it a useful material for demanding industrial fastening applications.
The external hexagonal head accommodates a metric wrench or socket, while the fully threaded shaft allows engagement with compatible nuts or tapped components. Following the ISO 4017 dimensional format, these ceramic screws offer a familiar fastening geometry for precision equipment, electrical systems, and chemical processing machinery.
Zirconia’s low thermal conductivity also helps restrict heat flow through the connection, supporting designs that require thermal separation.
