The JBO Thread Plug Gauge (NoGo) - Metric Fine is a precision inspection tool designed for metric fine threaded holes. It helps machinists, quality inspectors, and technicians quickly verify that threaded holes meet exact size and tolerance in components across manufacturing and maintenance settings. The NoGo designation helps you identify holes that are out of spec, reducing guesswork during assembly and trimming rework time.

Crafted for durability and consistent results, this gauge is made from hardened steel to resist wear in busy shops. It features a right-hand thread orientation and 6H tolerance for reliable, repeatable checks on M135 x 1.5 metric fine holes, making it a dependable choice for quality assurance and production environments.

• Hardened steel construction: Durable and wear-resistant for long tool life in demanding environments.
• Metric Fine NoGo size M135 x 1.5: Precise dimension for reliable Go/NoGo hole inspection of metric fine threads.
• Right-hand orientation with 6H tolerance: Ensures consistent fit with standard threaded holes and repeatable readings.

This plug gauge helps streamline your inspection workflow by delivering quick, decisive readings. Its robust build supports daily use on the shop floor, while its precise sizing reduces guesswork, minimizes rework, and supports compliant, repeatable part quality across production runs.
