Information on Ceramic Screws, Nuts, Bolts and Fasteners
Ceramic screws, nuts, and bolts are fastening components manufactured from either 99.5% Alumina (Al2O3) or Silicon Carbide (SiC). They are perfect for extreme applications where exceptional heat resistance, electrical insulation and chemical resistance are required.
Key features of Ceramic screws, nuts, bolts and fasteners include:
- Ceramic manufactured from either 99.5% high-purity alumina or Silicon carbide (SiC).
- Manufactured to DIN standards
- Continuous use at 1,500°C.
- Excellent heat resistance, chemical resistance, and electrical insulation.
- Special features such as ventilation holes and cleanroom washing available.

Material: Ceramic alumina screws, nuts, bolts and fasteners are primarily manufactured from alumina ceramic, which is a polycrystalline material with high hardness and strength. Ceramics have exceptional wear resistance, high temperature tolerance (up to 1,500°C) and chemical stability.
High Temperature Resistance: Ceramic exhibits excellent resistance to high temperatures (up to 1,500°C continuous). It can withstand extreme heat without significant deformation or loss of mechanical properties. This makes ceramic alumina screws, nuts, bolts and fasteners suitable for applications in high-temperature environments, such as satellites, vacuum furnaces and within the Oil and Gas industry.
Exceptional Hardness: Ceramics are known for their high hardness, ranking just below diamond on the Mohs scale. Ceramic screws, nuts, bolts and fasteners offer exceptional resistance to abrasion, wear, and surface damage. This makes them ideal for applications where components are subjected to friction or abrasive forces.
Corrosion Resistance: Ceramics are highly resistant to corrosion and chemical attack. They can withstand exposure to various acids, alkalis, and corrosive substances without degradation. Ceramic alumina screws, nuts, bolts and fasteners are commonly used in corrosive environments or industries where chemical resistance is essential, such as chemical processing applications.
Electrical Insulation: Ceramics are an excellent electrical insulator. Ceramic screws, nuts, bolts and fasteners do not conduct electricity, making them suitable for applications where electrical insulation is necessary, such as in electronic devices or high-voltage equipment.
Lightweight: Compared to metallic components, ceramic screws, nuts, bolts and fasteners are lightweight. This property is advantageous in applications where weight reduction is a priority, such as aerospace or automotive industries, where minimizing the overall weight of the components is crucial for fuel efficiency and performance.
Specialized Applications: Ceramic screws, nuts, bolts, and fasteners are designed for applications in a wide range of industries, including aerospace, automotive, electronics, semiconductor manufacturing, chemical processing, and high-temperature equipment. They are commonly used in environments where their unique combination of properties, including high temperature resistance, hardness, corrosion resistance, and electrical insulation, is advantageous.
