The JBO Thread Plug Gauge (GO) - Metric Fine - Right Hand - 4H - M55 x 2 is a precision go gauge designed to verify internal threads quickly and reliably. It’s built for machinists, inspectors, and quality teams who need fast, confident Go/No-Go checks on threaded holes, ensuring they meet the exact M55 x 2 specification and 4H tolerance.

• Precise Metric Fine Go Gauge (M55 x 2, 4H): Enables rapid, accurate go/no-go verification of internal threads, delivering consistent results that help speed up inspection and reduce guesswork.
• Hardened Steel Construction for Durability: Resists wear and deformation in tough workshop environments, maintaining accuracy over thousands of uses and extending tool life.
• Ergonomic Right-Hand Design: Easy to handle and aligns naturally with threaded holes, allowing fast checks and minimal setup time on busy production lines.

Using the gauge streamlines quality control by delivering reliable pass/fail decisions, reducing rework, and supporting reproducible results across batches. Its precise dimensions and rugged construction combine to lower maintenance costs while boosting confidence in assemblies that rely on accurate threading.
