The JBO Thread Plug Gauge is a metric fine Go/No-Go gauge engineered for precise internal thread inspection. It’s ideal for engineers, buyers, tradespeople, hobbyists, and technicians alike, providing a quick way to verify M38 x 0.5 right-hand threads and ensure components fit together reliably.

• Go/No-Go Design for Fast, Reliable Inspection: Quickly determine whether a threaded hole meets spec—the Go end confirms full depth and pitch, while the No-Go end reveals undersized or oversized threads to prevent improper assemblies.
• Durable Hardened Steel Construction: Built to withstand daily shop use, resisting wear and maintaining calibration over the long term for consistent results you can trust.
• Metric Fine Thread Precision: M38 x 0.5, Right-Hand, 6H: Specifically matched to common metric fine-thread standards, delivering reliable gauging results for high-precision applications.

Using the JBO Thread Plug Gauge helps streamline quality checks, reduce guesswork, and speed up setup times. With dependable readings, you’ll ensure proper thread engagement in assemblies, minimize rework, and improve overall workflow efficiency across manufacturing, maintenance, and repair tasks.
