Introducing the JBO Thread Ring Gauge (GO) — Metric Fine, Right Hand, 4h, M78 x 1.5. This precision ring gauge verifies external thread diameters quickly and reliably, making it an essential tool for engineers, machinists, quality inspectors, and workshop technicians alike. Crafted from hardened steel, the gauge offers durable wear resistance and long-lasting performance in demanding work environments. Its meticulous design and exact dimensions support repeatable inspections, helping you confirm components meet the required metric fine-thread standard at a glance.

• Precise GO gauge for metric fine threads: Quickly verify external thread diameters against the M78 x 1.5 fine-pitch standard, enabling fast pass/fail decisions during inspections.
• Durable hardened steel construction: Built from hardened steel for excellent wear resistance, delivering long tool life in busy workshops and demanding environments.
• User-friendly geometry for fast conformance checks: Clear, straightforward design makes it simple to identify properly conforming threads at a glance, speeding up quality checks and reducing rework.

Using the JBO Ring Gauge (GO) for metric fine threads improves inspection speed and reliability. It helps you confirm external threads meet the exact standard on first attempt, reducing guesswork and rework. The rugged construction and precise tolerances deliver repeatable results across operators and shifts, supporting tighter quality control, shorter production cycles, and greater confidence in assembled components.
