The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 4h, M13 x 0.5 is a precision inspection tool designed to verify external threads on fasteners and machined components. It provides a fast, clearly defined NoGo check so you can quickly confirm whether parts are within specification. Ideal for engineers, machinists, quality teams, and shop-floor inspectors, this gauge helps you make confident pass/fail decisions without guesswork.

In demanding environments, its hardened steel construction delivers lasting durability while maintaining precise dimensions for reliable readings across many uses. The metric fine thread calibration and right-hand orientation ensure compatibility with standard fasteners and components, enabling consistent results for M13 x 0.5 applications and beyond.

• Fast NoGo Pass/Fail for Quick QC: Provides an instant, obvious indication of out-of-spec threads, helping you weed out non-conforming parts in seconds and reduce rework.
• Hardened Steel Construction for Longevity: Built to withstand daily shop wear, maintaining sharp gauging edges and accuracy over many cycles.
• Metric Fine, Right-Hand Compatibility: Precisely calibrated for fine-pitch metric threads with right-hand threading, delivering consistent measurements for reliable results.

Used as part of a standard inspection routine, this gauge speeds up workflows, improves thread quality control, and supports compliant assembly and sourcing decisions. Its durability minimizes downtime and replacement costs, while its precise measurements empower you to maintain tight tolerances across batches and operations.
