The JBO Thread Plug Gauge is a precision tool designed for inspecting internal metric fine threads. Specifically tuned for M17 x 0.5 and a right-hand orientation, this Go/No-Go gauge lets you quickly confirm whether a threaded hole meets specification, reducing guesswork during setup and quality checks.

Featuring a rugged, knurled body for secure handling, the gauge is built to endure daily use in busy workshops. Its hardened steel construction delivers lasting wear resistance, helping you maintain accuracy across thousands of inspections while withstanding the demands of production environments.

• Go/No-Go quick verification: Enables fast pass/fail checks of internal threads with dedicated go and no-go ends, speeding up setups and inspection cycles while reducing guesswork.
• Metric fine thread compatibility (M17 x 0.5, Right Hand, 6G): Precisely tuned for metric fine holes, ensuring consistent, reliable acceptance criteria and compatibility with mating parts across suppliers.
• Durable, ergonomic hardened steel build: Hardened steel stands up to heavy use, and the knurled design provides a secure grip for accurate handling—even when wearing gloves.

This plug gauge helps you streamline workflows, cut downtime, and achieve dependable thread fits in every assembly. By delivering quick, repeatable inspections with a robust, long-lasting construction, it supports consistent quality and faster decision-making in both production lines and job sites.
