Material: Zirconia (ZrO₂)

Measurement System: Metric

Drive Type: Hexagon (External)

White

Continuous Maximum Temperature: 1200ºC

Flammability: Noncombustible

Ceramic (Zirconia ZrO₂) Hexagon Nuts - DIN 934 conform to the following Standards/Norms:

ISO 4032

DIN 934

CSN 021401

PN 82144

UNI 5588

DIN 934 zirconia hexagon nuts provide secure threaded fastening in assemblies requiring electrical isolation, corrosion resistance, or freedom from magnetic interference. Their standard hexagonal profile supports straightforward installation with conventional spanners, while the ZrO₂ ceramic construction performs reliably in environments where metallic nuts may conduct, corrode, or contaminate.

Zirconia combines high compressive strength and surface hardness with greater fracture toughness than many engineering ceramics. Typical applications include semiconductor production, analytical instruments, electrical equipment, chemical-processing systems, cleanrooms and specialist machinery.

Technical benefits:

  • DIN 934 hexagon nut form
  • High-strength zirconia ceramic
  • Electrically insulating and non-magnetic
  • Resistant to corrosion, chemicals and wear
  • Low thermal conductivity
  • Clean, metal-free fastening solution
  • Suitable for precision engineering applications

Zirconia (ZrO₂) Key Properties

  • 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.
