Measurement Precision & Tolerances

Plain Plug Gauges are solid cylindrical gauges ground to specific diameters used for direct go/no-go checks. They are simple, rugged and ideal for high-throughput environments. Select the tolerance class and fit (e.g., H7/g6 equivalents) to match engineering requirements.

Calibration & Compliance

Calibration against master standards is required to ensure accuracy; calibration certificates from accredited labs are recommended for audit and supplier validation.

Processing Insight & Technical Notes

Ensure plugs are clean before use and handle them to avoid nicks. For tight tolerances, store gauges in protective cases and verify diameter periodically with a micrometer or CMM traceability.

Applications & Use Cases

• Incoming QA: Rapid acceptance checks on bore dimensions before inventory storage.
• Production Line: Simple go/no-go checks during machining to reduce scrap.
• Quality Audits: Use as reference tools during supplier audits and verification.
