The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6e, M20 x 1.5 is a precision inspection tool designed to verify external thread diameters on metric fasteners. Suitable for manufacturers, machinists, quality control teams, and maintenance staff, it provides a fast, reliable go/no-go check to confirm threads meet required limits.

Crafted from hardened steel, the gauge resists wear in busy workshops, delivering long service life and stable measurements across many inspections. Its straightforward, user-friendly design makes it easy to identify non-conforming components quickly, supporting efficient quality control workflows.

• Go/No-Go verification for metric fine threads: Quickly determines whether an M20 x 1.5 thread is within the maximum limit and flags non-conforming parts, speeding up inspections and reducing rework.
• Hardened steel construction for durability: Built to endure daily handling in busy environments, resisting wear to maintain accurate measurements over time.
• User-friendly, grip-friendly design with clear identification: Knurled edge for secure handling and easy reading of markings, enabling fast checks in tight spaces and smooth QC workflows.

This gauge helps streamline thread inspection, reduce downtime, and improve consistency across production runs. With robust construction and a straightforward Go/No-Go check, you can rely on accurate, repeatable decisions that enhance overall workflow efficiency and product quality.
