JBO Thread Ring Gauge (NoGo) for Metric Fine threads is a precision inspection tool designed to verify external thread sizes quickly and reliably. Ideal for machinists, quality inspectors, and production teams, it helps confirm that components meet the required metric standard before assembly or further machining. This NoGo gauge is specifically configured for Right Hand threads at M28 x 0.5 with a 6g tolerance class, ensuring consistent results across jobs.

Crafted from hardened steel, the gauge delivers durable performance in busy workshops. Its robust construction resists wear, maintaining accurate dimensions through frequent use. The NoGo design provides a clear pass/fail indication, making it easy to spot non-conforming parts and keep production moving.

• Durable Hardened Steel Construction: Built to last in demanding environments, it resists wear and maintains precise ring dimensions for long service life.
• Precise Metric Fine Thread Compatibility (M28 x 0.5, 6g): Ensures accurate external thread checks against the standard, enabling reliable pass/fail decisions and reducing measurement guesswork.
• Clear NoGo Verification for Quick QC: The NoGo design gives an unambiguous indication when a thread is out of tolerance, speeding up quality control and minimizing inspection time.

The JBO NoGo Thread Ring Gauge helps you streamline inspection workflows by delivering fast, dependable checks on external metric threads. It supports consistent quality across batches, reduces rework, and boosts confidence in your threading processes—from production floors to quality labs—so you can finalize parts with certainty and keep your operations moving smoothly.
