The Asimeto Ring Thread Gauge (NoGo) is a precision metric gauge built for quick, reliable checks of 6g coarse threads on M3 x 0.5 fasteners. Designed for quality teams, machinists, and suppliers, it provides a clear guardrail to confirm parts stay within the lower-size limit.
- Thread Size: Metric coarse 6g threads, M3 x 0.5, right-hand orientation
- No-Go Function: Verifies minimum material condition to ensure the part remains within the lower limit of the size specification
- Calibration: Precisely calibrated to keep the thread within tolerance for consistent, repeatable checks
- Construction: Durable, precision‑made ring gauge designed for repeated use in busy shop environments
- Intended Use: Ideal for incoming inspection, in‑process checks, and QC workflows where accurate thread size control matters
Using the NoGo gauge accelerates quality control by providing a straightforward pass/fail assessment for threaded components. It helps prevent oversized or undersized parts from advancing to assembly, reduces rework, and supports reliable part interchangeability across production runs. This gauge is particularly suited for teams handling metric coarse-threaded parts and seeking consistent, measurable outcomes in their inspection procedures.
