The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6h, M15 x 1.5 is a precision external thread gauge designed to verify threaded components quickly and reliably. Ideal for engineers, machinists, quality teams, and workshop technicians, it helps confirm that external threads conform to the metric fine standard on right‑hand threads.

Designed as a NoGo gauge, it provides an immediate signal when a thread is out of tolerance, reducing ambiguity during inspection. Crafted from hardened steel with a wear‑resistant finish, it stands up to daily use in demanding environments while preserving accuracy and consistency.

• Accurate NoGo verification for metric fine threads: The NoGo gauge helps inspectors determine if external threads meet the M15 x 1.5 (6h) specification. If the gauge threads onto the component, the thread is out of tolerance, enabling fast, clear decisions and reducing rework.
• Durable hardened steel construction: Built to withstand daily shop wear, the gauge maintains dimensional stability and long service life even in busy production lines.
• User-friendly, quick‑read identification: Clear markings and a design that makes it easy to recognize compliant versus non‑conforming parts at a glance, speeding up quality checks and minimizing operator error.

Using the JBO NoGo Thread Ring Gauge helps you lock in consistent thread quality across batches, streamline inspections, and improve overall workflow. With its precise metric fine dimensions and rugged construction, you can rely on repeatable results, fewer scrap parts, and faster determination of fit during assembly or maintenance projects.
