Ceramic (Alumina) Hex Socket Cylinder Head Cap Metric Screws conforming to ISO 4762 are engineered for extreme operating environments requiring exceptional hardness, electrical insulation, and high-temperature stability. Manufactured from high-purity Alumina (Al₂O₃) ceramic, these fasteners provide outstanding wear resistance, corrosion resistance, and dimensional stability in applications where conventional metals and polymers cannot perform.
Their hex socket drive and cylinder head design allow secure fastening so their excellent mechanical integrity under elevated temperatures and chemically aggressive conditions can be applied. Their non-magnetic and electrically insulating properties make them particularly suitable for semiconductor processing, laboratory equipment, and high-voltage applications.
These screws are widely used in semiconductor equipment, furnaces, laboratory apparatus, electrical insulation systems, and high-temperature industrial applications requiring non-metallic fasteners with exceptional durability and chemical resistance.
