The JBO Thread Plug Gauge (NoGo) – Metric Fine is a precision tool used to verify threaded holes with metric fine threads. It helps machinists, inspectors, and maintenance teams quickly confirm parts meet their size and tolerance requirements.

Built for durability in demanding environments, this NoGo gauge uses hardened steel and a knurled body for a secure, repeatable grip. Sized for Right Hand M82 x 1.5 threads with a 6H tolerance, it delivers reliable checks across production runs and service work.

• Fast NoGo hole verification: Quickly confirm that threaded holes do not exceed the specified metric fine size, enabling decisive pass/fail checks and reducing inspection time.
• Rugged, wear‑resistant construction: Hardened steel with a knurled body provides durability and a secure grip, even in busy workshops or with work gloves on.
• Precise, standard-sized fit: Precisely sized for Right Hand M82 x 1.5 threads with a 6H tolerance, ensuring consistent measurements and repeatable results across parts and shifts.

This gauge supports reliable quality control by delivering consistent, straightforward measurements that help you move parts through inspection faster, reduce rework, and maintain high standards across your manufacturing or maintenance operations.
