The JBO Thread Ring Gauge (GO) – Metric Coarse, Right Hand, 6e, M20 x 2.5 is a dedicated precision inspection tool designed to verify external threads on metric coarse fasteners and components. It’s ideal for engineers, machinists, quality teams, and workshop technicians who rely on fast, repeatable go/no-go checks to ensure thread fit and compatibility.

Manufactured from hardened steel, this GO gauge delivers exceptional durability and wear resistance in demanding production environments. Its simple, robust design supports accurate measurements during incoming inspection, in-process checks, and final assembly, confirming that M20 x 2.5 metric coarse threads meet industry standards and specifications.

• Go/No-Go accuracy for reliable thread verification: Quickly confirm external M20 x 2.5 coarse threads meet tolerance limits to prevent misfits and rework, helping you capture quality issues at the source and maintain consistent results.
• Hardened steel construction for long service life: Built to withstand daily handling and wear in busy QC workflows, maintaining calibration and delivering repeatable measurements over time.
• User-friendly right-hand metric coarse design: Intuitive orientation and fast engagement with standard coarse-thread parts, enabling rapid inspections and reduced setup time in busy production environments.

By using the JBO GO Ring Gauge, you gain a reliable, efficient way to verify thread fit before assembly, speeding up workflows, reducing downtime, and ensuring every M20 x 2.5 threaded connection threads smoothly and functions as intended. This gauge supports traceable quality control and confident, consistent results across your production line.
