The JBO Thread Ring Gauge (GO) is a precision tool designed to verify external metric threads with speed and confidence. It is specifically configured for metric fine threads and is labeled for Right Hand, 6h tolerance, and M34 x 1.5, making it a reliable choice for engineers, machinists, and quality teams alike.

Manufactured from hardened steel, this GO ring gauge delivers durable, wear-resistant performance in busy workshops. The knurled outer edge provides a secure grip for quick setup and handling, while its exact dimensions simplify quick identification of parts that conform to your standards.

• Precision GO Gauge for Metric Fine Threads (M34 x 1.5, 6h, Right-Hand): Ensures external thread diameters conform to exact metric fine standards, enabling fast, confident inspections and pass/fail decisions in minutes.
• Hardened Steel Construction for Long-Life Durability: Built to resist wear and maintain accuracy in demanding production environments, reducing replacement costs and downtime.
• Ergonomic, Knurled Ring for Easy Handling and Quick Go/No-Go Checks: The knurled edge provides a secure grip and fast alignment, helping technicians identify conforming parts at a glance and speeding up QC workflows.

By pairing precise sizing with rugged construction and intuitive handling, this gauge helps you streamline quality control, cut inspection time, and reduce rework across batches. Use it for incoming part verification, in-process checks, or setting up equipment to ensure every threaded connection meets your standards with repeatable, reliable results.
