Choose a ceramic screw when the fastener itself must withstand heat, resist corrosion, or provide electrical isolation. This collection brings together alumina (Al₂O₃) screws and zirconia (ZrO₂) screws for specialised equipment and demanding environments.
Key properties
-
Electrical insulation: Both ceramics can help prevent an unwanted conductive path.
-
Heat and chemical resistance: Suitable for applications where the operating environment affects material choice.
-
Alumina: Valued for its hardness and high-temperature stability.
-
Zirconia: Offers greater toughness than alumina where resistance to cracking is a priority.
Ceramic screws are used in electrical equipment, laboratory instruments, heat-treatment systems and chemical-processing machinery. The right material depends on the assembly: consider the operating temperature, chemical exposure, load, and mating components before selecting a screw.
Browse alumina and zirconia options by material, head style, and size. Check each product’s specifications and tightening guidance, as ceramic fasteners can fracture if overloaded.
