Ceramic Composite Screws

Ceramic Composite Screws are advanced, non-metallic fasteners that excel in extreme operational environments, specifically where metallic screws would fail due to excessive heat, chemical attack, or electrical conductivity. These screws, typically fabricated from engineered ceramics like Alumina or Zirconia composites, offer exceptional dimensional stability and maintain high compressive strength at temperatures reaching over 1000 °C. They are critically important as electrical insulating screws in high-power systems and are preferred for use as non-magnetic screws in sensitive measurement equipment and MRI machines. Zeron Fastners is a specialized supplier and manufacturer in India, providing a range of precision-manufactured ceramic composite screws for technical, high-specification assemblies.
