The JBO Thread Ring Gauge (NoGo) in Metric Fine is a precision tool for verifying external threads on fasteners, sleeves, and mating components. Specifically configured for right-hand M27 x 1 threads, this gauge helps inspectors and machinists confirm that parts meet the required diameter and pitch with consistent, repeatable results. Its NoGo designation means you quickly identify under- or over-tolerance parts during routine QC.

Crafted from hardened steel, the gauge delivers durability and wear resistance in busy workshops. The robust construction stands up to daily use, maintaining accuracy even after repeated insertions and withdrawals, making it a reliable part of your quality control toolkit.

• Precise metric fine thread verification (M27 x 1): Quickly determines if external threads meet the exact diameter and pitch for 6g tolerance, with a clear Go/NoGo result to guide pass/fail decisions.
• Durable hardened steel construction: Built to withstand the rigors of daily workshop use, offering long life, minimal wear, and reliable performance in challenging environments.
• User-friendly NoGo design for fast QC: Simple, intuitive checks that reduce inspection time and downtime, enabling both seasoned and new operators to identify non-conforming parts at a glance.

This gauge helps you streamline your inspection workflow, minimize rework, and ensure components meet exact threading standards. By providing quick, dependable verification, it supports consistent assembly quality and confidence in every build or repair.
