The JBO Thread Ring Gauge GO (Right Hand, Metric Fine) – M15 x 1.5 is a precision inspection tool designed to verify external thread diameters quickly and reliably. Ideal for engineers, machinists, quality control teams, and maintenance staff, it helps confirm that threaded components meet the exact M15 x 1.5 specification and ensures consistent fit across assemblies.

Crafted for durability in busy workshops, this gauge uses hardened steel to resist wear and maintain accuracy over many uses. Its straightforward, intuitive design makes it easy to slip into tool kits and perform fast, confident go/no-go checks on threaded parts, helping you streamline inspections on the shop floor.

• Precision Go/Nogo for Metric Fine Threads: Delivers fast, unambiguous go/no-go checks for external threads in the metric fine range, including M15 x 1.5, speeding up inspection without guesswork.
• Hardened Steel Construction for Longevity: Built to resist wear and corrosion, delivering consistent measurements and a longer gauge life in demanding environments.
• Clear, User-Friendly Design: Designed for easy alignment with threads, promoting quick identification of conforming parts and reducing reading errors on the shop floor.

This gauge helps streamline quality control, reduce downtime, and improve overall accuracy across your threaded components. By delivering reliable, repeatable results, it supports tighter process control, minimizes rework, and enhances confidence in every assembly or field service operation—from routine maintenance to high-volume production.
