The JBO Thread Plug Gauge is a precision inspection tool designed to verify metric fine-thread holes with confidence. It’s ideal for engineers, machinists, inspectors, and workshop professionals who need to guarantee that threaded components fit together smoothly and consistently. This Go/No-Go gauge provides a fast, reliable check that helps prevent misthreads and assembly delays.

• Go/No-Go Quick Verification: Quickly determine if a hole meets tolerance by testing the “go” and “no-go” limits, delivering clear pass/fail results to speed up quality checks.
• Metric Fine Thread Precision (M34 x 1.5): Specifically engineered for metric fine threads, ensuring accurate verification for precise applications such as M34 x 1.5 with dependable repeatability.
• Durable Hardened Steel Construction: Built to endure frequent use in busy shops, resisting wear and maintaining measurement accuracy over time.

Using the JBO Thread Plug Gauge helps streamline threaded-hole inspections, reduce rework, and improve first-time assembly outcomes. Its robust construction translates to longer service life in demanding environments, supporting consistent performance and workflow efficiency across teams.
