The JBO Thread Plug Gauge (NoGo) — Metric Fine, Right Hand, 6H, M102 x 2 — is a precision tool designed to verify threaded holes for metric fine threads. It helps engineers, quality inspectors, machinists, and hobbyists quickly confirm that holes meet required specifications, delivering clear pass/fail results without guesswork.

Built for durability and long-lasting accuracy, this gauge uses hardened steel to resist wear in busy workshop environments. Its metric fine thread design ensures consistent engagement and repeatable checks across parts and production runs.

• Metric fine-thread precision: Specifically engineered to measure metric fine holes, delivering dependable results that support tight tolerances.
• Durable hardened steel construction: Resists wear and maintains accuracy over time, even in demanding applications and busy shops.
• Right-hand NoGo gauge with 6H, M102 x 2 sizing: Provides reliable, repeatable go/no-go checks aligned with standard thread specifications for fast, confident inspections.

Using this gauge helps streamline quality control, reduce rework, and improve overall workflow by delivering quick, trustworthy verification of hole quality. It supports consistent performance across parts and batches, enabling you to validate compliance with your dimensional standards with ease.
