Ceramic (Zirconia ZrO₂) Hex Socket- Cylinder Head Cap Screws - DIN 912

Temperature Stability: Zirconia retains mechanical strength better than many engineering materials at elevated temperatures, with a maximum service temperature of up to 1200ºC in highly controlled or inert atmospheres.

Chemical Resistance: This material has excellent resistance to acids, alkalis, solvents, saltwater, and oxidation.

Electrical Insulation: Zirconia screws are ideal where electrical isolation is required, galvanic corrosion must be avoided, and non-conductive assemblies are needed.

High Mechanical Strength: Zirconia is one of the strongest engineering ceramics available. Compared with alumina ceramics, zirconia offers significantly higher toughness and impact resistance.

Non-Magnetic: making it suitable for MRI equipment, electronics manufacturing, semiconductor systems and scientific instrumentation.

High Purity / Cleanroom Compatibility: Zirconia generates very low contamination and is commonly used in semiconductor wafer handling, vacuum systems, medical devices, and cleanroom equipment

Corrosion Resistance: Unlike metals, zirconia does not rust or oxidize significantly and is immune to galvanic corrosion.

Biocompatibility: Zirconia is widely used in medical and dental applications because it is biocompatible, non-toxic, chemically inert and non-allergenic.

Dimensional Stability: Ceramic Zirconia is able to have minimal creep at moderate temperatures, excellent shape retention, low deformation under load, and stable precision tolerances.

Acoustic Properties: The high stiffness gives good vibration transmission for acoustic applications and is used in specialist audio and instrumentation applications.

Optical Properties: Zirconia can be partially translucent in specialized grades and has high refractive index properties.

Oxidation & Environmental Stability: Zirconia has oxidation and environmental stability as it is highly resistant to oxidation, moisture, steam, and most corrosive atmospheres.
