Asimeto’s 686 Series NoGo Ring Gauge provides a precise, reliability‑focused way to verify metric external threads. Designed for M27 x 1 right‑hand fasteners, this ring gauge helps ensure only correctly sized threads are used in critical assemblies.

• Series: 686 Series NoGo Ring Gauge for metric external threads (6g tolerance)
• Thread Size: M27 x 1, Right‑Hand (RH) thread gauge
• Designation: NoGo to confirm that the pitch diameter does not exceed the maximum allowable size
• Function: Used to determine if threads are out of tolerance by failing to pass the NoGo check
• Material & Construction: Built with high‑quality materials for durability and long‑lasting performance
• Grip & Handling: Knurled outer edge for secure handling during inspection

In practice, this gauge supports a streamlined QC workflow: if a fastener cannot pass through the NoGo gauge, the thread pitch diameter is too large, preventing mismatches and potential failures in assembled products. The 686 Series is engineered for repeatable, stable measurements in busy production environments, helping teams maintain consistent thread quality over time.
