JBO Thread Plug Gauge (NoGo) - Metric Fine - Right Hand - 6H - M118 x 2

The JBO Thread Plug Gauge (NoGo) - Metric Fine is a precision inspection tool designed for checking internal threads in holes that use metric fine pitch. This NoGo plug gauge is tailored for M118 x 2 with a 6H tolerance and right-hand threads, making it ideal for machinists, quality control inspectors, engineers, and workshop technicians who need quick, reliable go/no-go verification during manufacturing or assembly.

Constructed from hardened steel for long-lasting accuracy, the gauge resists wear and maintains its dimensions even under repeated use in busy workshops. Its rugged, corrosion-resistant finish stands up to everyday inspection tasks, giving you confidence you’ll get consistent results day after day.

• NoGo precision gauge for metric fine threads: Verifies that internal threads meet the M118 x 2, 6H, right-hand specification by blocking holes that are out of tolerance, delivering a clear pass/fail result and reducing guesswork in QA.
• Durable hardened steel construction: Built to endure daily use in busy shops while preserving measurement integrity and resisting wear over time.
• Ergonomic, consistent testing experience: Knurled grip and a precisely machined plug design enable quick, repeatable checks with minimal fatigue and fewer handling errors.

Using the JBO NoGo gauge speeds up inspections, reduces rework, and improves the reliability of threaded assemblies. With its precise metric fine threading and robust build, you can trust it to deliver consistent results across daily use in manufacturing, assembly, or service environments. This gauge is a practical addition to any quality control toolkit, helping you make faster, more confident pass/fail decisions with every check.
