The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6g - M30 x 1 is a precision inspection tool designed to verify external thread diameters on fasteners, sleeves, and machined components. Built for engineers, inspectors, machinists, and workshop staff, it provides fast, reliable NoGo checks to confirm that threads conform to the M30 x 1 specification.

Crafted from hardened steel for durability and wear resistance, this gauge maintains dimensional stability even under heavy use. The Right Hand orientation and a compact 6g weight deliver a comfortable, balanced feel on the shop floor, making routine thread inspections quick, repeatable, and easy to perform.

• NoGo metric fine design: Precise NoGo limit tailored to M30 x 1 external threads, enabling quick pass/fail checks of diameter and pitch to ensure accurate thread form and tolerance compliance.
• Hardened steel construction: Built to endure busy production environments, delivering long service life and stable measurements even after repeated insertions and withdrawals.
• Ergonomic, lightweight right-hand gauge: Designed for comfortable handling on the job, helping inspectors work faster with reduced fatigue and clearer, repeatable results.

Using the JBO Thread Ring Gauge simplifies quality control by quickly identifying non-conforming parts, reducing rework, and improving overall workflow. Its reliable performance supports tighter tolerances, faster inspections, and greater confidence that threaded components meet specification before assembly or shipment.
