Ceramic screws AND nuts

Ceramic screws, nuts and bolts are fastening components made of 95% alumina (Al2O3). They are perfect for extreme applications where exceptional heat resistance, electrical insulation and chemical resistance are required.
The main features of ceramic screws, nuts and fasteners include:
- Ceramics made of 95% high purity alumina
- Manufactured according to DIN standards
- Continuous use at high temperatures 1,400/1,500°C
- Excellent resistance to chemicals even in the presence of heat
- Excellent electrical insulation
- Perfect fit and excellent mechanical seal
 
Technical ceramic store screws and nuts are made of ceramic alumina, a polycrystalline material with high hardness and strength. Our ceramics have exceptional wear resistance, high temperature tolerance and chemical stability. Therefore suitable for applications in high temperature environments, such as satellites, vacuum furnaces and in the petrochemical sector
Screw and Nut are produced with metric pitch and thanks to our rigorous controls and the grinding process we guarantee a perfect ceramic/ceramic and ceramic/metal coupling or with any other material with the same metric thread.

OTHER ADVANTAGES OF ALUMINA SCREWS AND NUTS

Ceramics are known for their high hardness, just below that of diamond on the Mohs scale. Ceramic screws, nuts and bolts offer exceptional resistance to abrasion, wear and surface damage. This makes them ideal for applications where components are subjected to frictional or abrasive forces.
 
Alumina is highly resistant to corrosion and chemical attack. It can withstand exposure to various acids, alkalis and corrosives without degrading.
 
Ceramics are excellent electrical insulators. Ceramic screws, nuts and bolts do not conduct electricity and are therefore suitable for applications where electrical insulation is required, such as in electronic devices or high voltage equipment.
 
Compared to metal components, ceramic screws and nuts are lightweight. This property is advantageous in applications where weight reduction is a priority, such as in the aerospace or automotive industries, where minimizing the overall weight of components is critical to fuel efficiency and performance.
 
They are used in all environments where their unique combination of properties, including high temperature resistance, hardness, corrosion resistance and electrical insulation, is essential. As in the Aerospace sector, in the Medical sector being non-magnetic, completely inert at an environmental level and thanks to the anti-interference properties.
Also in the naval sector for resistance to acids, alkalis and corrosion, to extend the useful life of the equipment in which they are used.
 
 

Why choose ceramic screws and nuts?

 
Electrical insulation
Our technical ceramic fixing systems guarantee high electrical insulation and are completely non-magnetic.
Heat resistance
They are made to guarantee the highest standards of resistance to high temperatures.
Corrosion resistance
Thanks to purity and high percentage of alumina, they are used in corrosive environments and extreme conditions.
