CNC Machined Threaded Quartz Screw
CNC machined threaded quartz screws are high-precision fastening components made from fused silica (quartz glass), manufactured using advanced Computer Numerical Control (CNC) machining to achieve exact thread profiles, pitch accuracy, and dimensional stability. These screws combine the exceptional properties of quartz—such as thermal resistance, chemical inertness, and optical clarity—with the mechanical precision required for specialized industrial, scientific, and optical applications.Key Features & Advantages
✔ Ultra-Precise Threading – CNC machining ensures tight tolerances (typically within ±0.01mm) for metric, imperial, or custom thread profiles (e.g., M3, M6, UNC, UNF).
✔ Extreme Thermal & Chemical Resistance – Withstands temperatures up to 1200°C and resists acids, plasmas, and corrosive environments.
✔ Optically Transparent – Suitable for UV, laser, and photonic applications where metal screws would interfere.
✔ Non-Conductive & Non-Magnetic – Ideal for semiconductor, vacuum, and high-frequency applications where electrical isolation is critical.
✔ Customizable Designs – Available in various head types (hex, flat, torx), thread lengths, and surface finishes (polished, frosted, coated).
Common Applications
Semiconductor & Vacuum Systems – Wafer handling, plasma etch chambers, CVD reactors.
Optics & Laser Technology – Precision alignment screws for lenses, mirrors, and fiber optics.
Medical & Analytical Instruments – Biocompatible fasteners for spectroscopy, endoscopy, and lab equipment.
Aerospace & Defense – Sensor mounts, optical housings, and thermal-resistant fixtures.
Research & High-Tech Engineering – Custom fasteners for synchrotrons, particle detectors, and cryogenic systems.
Why Choose Quartz Screws Over Metal or Plastic?
No outgassing – Critical for ultra-high vacuum (UHV) environments.
No thermal expansion mismatch – Prevents loosening under temperature cycling.
Corrosion-proof – Performs in harsh chemical or plasma conditions where metals degrade.
Customization Options
Thread Type: Metric, fine pitch, left-hand, multi-start, or proprietary designs.
Material Enhancements: OH-free fused silica for reduced UV absorption, or coated variants for improved grip.
Secondary Processing: Fire-polishing, laser engraving, or precision grinding for critical fits.
