The JBO Thread Ring Gauge GO Metric Fine is a precision inspection tool designed to verify external thread diameters quickly and reliably. Built for professionals across manufacturing, quality control, and maintenance, it helps confirm that parts meet the M148 x 1.5 standard with confidence. Crafted from hardened steel, this gauge is designed to endure demanding shop environments and continuous use without compromising accuracy. Its GO gauge design makes it easy to identify properly conforming threaded components at a glance, supporting efficient quality checks and consistent results.

• Fast GO checks for metric fine threads: Quickly determine if external threads meet the M148 x 1.5 size, enabling rapid pass/fail decisions and reducing inspection time.
• Durable hardened steel construction: Resistant to wear and deformation in busy workshops, delivering long-lasting performance and stable measurements over time.
• Ergonomic, repeatable performance: Right-hand orientation with a compact 6 g weight provides comfortable handling and consistent results across operators and jobs.

Used in quality control labs, machine shops, and field maintenance, this GO ring gauge helps streamline workflows by delivering reliable conformance checks that support tighter tolerances, fewer reworks, and improved overall accuracy in threaded components.
