FAQ

1. What is the difference between models?

All models share the same H8 tolerance and structure. The only difference is the diameter size (Ø2mm–Ø100mm). Each SKU represents a specific size.

2. Accuracy vs Resolution – what’s the difference?

• Accuracy (H8): Defines the allowable tolerance range for the hole
• Resolution: Not applicable, as this is a limit gauge without numerical output

3. Manual vs Digital gauges – which should I choose?

• Plug Gauge: Best for fast Go/No-Go inspection in production
• Digital Measuring Tools: Provide actual measurement values but require more time and calibration

For efficiency, plug gauges are preferred in batch inspection.

4. Which industries use H8 plug gauges?

Typical applications include:

• Automotive
• General machining
• Metal fabrication
• Equipment manufacturing

5. Is customization available?

Yes, customization options include:

• Other tolerance grades (H7, H6, G7, P7, etc.)
• Custom sizes and non-standard dimensions
• Special packaging or labeling requirements
• Calibration certificates per ISO standards
