FAQ
1. What is the difference between models?
Models differ by diameter and pitch combination (e.g., M10×1 vs M10×1.25), enabling selection based on specific thread design requirements.
2. Accuracy vs Resolution — what applies here?
- Accuracy: Defined by DIN13 tolerance class 6H
- Resolution: Not applicable, as this is a limit gauge
3. Manual vs Digital — where does this product fit?
This is a manual inspection gauge, designed for pass/fail verification rather than numerical measurement.
4. Which industries typically use this product?
- Aerospace (fine pitch threads widely used)
- Automotive
- Precision engineering
- Industrial manufacturing
5. Is customization available?
Yes, customization options include:
- Special thread pitches or diameters
- Different tolerance classes
- OEM branding and packaging
- Calibration certificates (traceable)
