Ceramic (Alumina) Hex Head Metric Screws manufactured to ISO 4017 standards are high-performance technical ceramic fasteners designed for applications requiring exceptional temperature resistance, electrical insulation, and corrosion resistance. Manufactured from high-purity Alumina (Al₂O₃), these screws provide outstanding mechanical stability and reliability in environments where conventional metal and plastic fasteners may fail.
The hex head design enables secure installation using standard spanners and sockets, providing reliable torque transfer and consistent clamping performance while allowing for straightforward assembly and maintenance. This design is particularly beneficial in applications where precise fastening, dimensional stability, and resistance to extreme operating conditions are required. The robust head configuration also helps ensure secure engagement with installation tools, making these screws suitable for use in demanding industrial, scientific, and research environments where long-term reliability is essential. Alumina ceramic hex head screws are widely used in semiconductor processing equipment, furnaces, laboratory systems, electrical insulation assemblies, vacuum systems, and high-temperature industrial equipment where thermal stability and material purity are critical.
Alumina ceramic offers excellent resistance to chemicals, oxidation, and wear while maintaining its properties at temperatures far beyond the capabilities of engineering plastics. Its electrically insulating and nonmagnetic characteristics make it particularly suitable for specialized applications where conductivity must be eliminated.
Available in a range of metric thread sizes and lengths.
