The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. It’s ideal for machinists, inspectors, and production teams that need quick, reliable confirmation that threaded holes meet exact specifications. With its Go/No-Go design, you can speed up quality checks and ensure every component will assemble correctly.

This gauge features a right-hand, metric fine thread specification (M38 x 1, 6G) and a durable hardened steel construction. The Go/No-Go requirement provides an accurate pass/fail result at a glance, helping you reduce guesswork and rework while maintaining tight tolerances in high-volume environments.

• Go/No-Go quick-check design: Enables fast pass/fail verification of thread holes, speeding setup and reducing inspection time without sacrificing accuracy.
• Durable hardened steel construction: Built to withstand daily use in busy workshops, resisting wear to maintain consistent measurement performance over time.
• Right-Hand metric fine thread spec (M38 x 1, 6G): Ensures precise, repeatable testing aligned with common metric components for reliable fits and quality control.

Using the JBO Thread Plug Gauge helps you streamline quality assurance, shorten assembly cycles, and achieve dependable threaded fits across parts and assemblies. Its robust design and straightforward Go/No-Go checks support accurate results, even in demanding manufacturing environments.
