The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, 4h, M18 x 2 is a precision go gauge designed to verify external thread diameters on fasteners, fittings, and machined parts. It’s ideal for engineers, machinists, quality inspectors, and shop technicians who need quick, reliable confirmation that a thread will mate with the specified M18 x 2 size.

Crafted from hardened steel for durability, this gauge delivers wear resistance and long-lasting accuracy in busy workshop environments. Its metric fine standard and right-hand orientation align with common industry practices, helping inspections stay consistent and efficient.

• Metric Fine Go Gauge (M18 x 2): Quick go/no-go verification of the external thread size to confirm parts meet the exact M18 x 2 specification, reducing inspection time and rework.
• Hardened steel construction: Built to withstand daily use and resist wear, maintaining accurate measurements over many cycles of insertion and removal.
• Right-Hand, 4h tolerance compatibility: Optimized for standard right-hand threads and 4h tolerance, ensuring consistent, repeatable measurements across lots and simplifying quality checks.

Using the JBO Thread Ring Gauge streamlines your quality control workflow by providing fast, reliable pass/fail results. Its robust construction and precise dimensions help you avoid misfits, reduce downtime, and deliver consistent performance across production runs.
