The JBO Thread Ring Gauge (GO) - Metric Fine, Right Hand, 6h, M20 x 1.5 is a precision inspection tool designed to verify external thread diameters quickly and reliably. It’s ideal for machinists, quality inspectors, and maintenance teams who need to confirm that threaded components meet exacting metric standards (fine pitch) without guesswork.

Designed for right-hand metric fine threads such as M20 x 1.5 and tuned to a 6h tolerance, this GO gauge aligns with standard inspection practices. Crafted from hardened steel, it resists wear and maintains accuracy in demanding workshop environments, supporting consistent results across daily use.

• Precise metric fine GO gauge: Delivers accurate external thread checks for M20 x 1.5 and similar fine pitches, helping you quickly confirm compliance and reduce rework.
• Rugged hardened steel construction: Built to resist wear and maintain accuracy through repeated use in busy workshops and production lines.
• Clear, quick go/no-go reading: Facilitates fast, unambiguous identification of conforming parts, speeding quality checks and cutting downtime.

Using the JBO Thread Ring Gauge (GO) – Metric Fine ensures consistent thread verification across teams and shifts. It reduces inspection time, lowers the risk of incorrect assemblies, and supports repeatable, reliable results in precision manufacturing and maintenance. With its durable construction and straightforward use, you can trust it to deliver confident pass/fail decisions and help keep production moving smoothly.
