This JBO Thread Ring Gauge (GO) is a precision tool for inspecting external threads on fasteners, fittings, and mating components. It’s ideal for engineers, machinists, quality teams, and workshop technicians who need quick, reliable verification that metric fine threads conform to standard specifications.

Built for everyday shop use, the hardened steel body resists wear and maintains dimensional accuracy, helping you maintain consistent quality across production runs.

• Precise metric fine threading (M9 x 0.75, right-hand, 6g): Quickly verify that external threads meet the GO standard for this common size and fit, speeding up setup and inspection with a clear pass/fail result.
• Hardened steel construction for durability: Designed to endure daily use in busy shops, resisting wear while preserving accurate measurements over time.
• Clear GO indication for fast quality checks: Enables quick identification of compliant threads, reducing rework and downtime during inspections.

With the JBO Thread Ring Gauge, you gain a reliable, repeatable method to confirm external thread dimensions, helping you accelerate inspections, improve first-pass yields, and keep assemblies within specification. The hardened steel design ensures long service life in demanding environments, while the metric fine M9 x 0.75 right-hand threading coverage supports a wide range of components. Use this GO gauge as part of your quality-control workflow to streamline setup, save time, and reinforce confidence in every threaded connection.
