The JBO Thread Plug Gauge is a precision tool designed to quickly verify metric fine-thread holes. It’s ideal for machinists, quality control specialists, engineers, and workshop teams who need reliable, on-the-spot confirmation that internal threads meet exact specifications.

Designed for metric fine threads, this gauge targets M33 x 2 with a right-hand thread pattern and 6G tolerance, ensuring accurate checks that align with common industrial standards. The Go/No-Go design delivers a clear pass/fail result, speeding up inspections and reducing downtime in busy production environments.

• Go/No-Go verification for fast tolerance checks: Quickly determine if the internal thread hole is within spec, enabling faster pass/fail decisions and minimizing downtime.
• Metric fine-thread compatibility (M33 x 2, 6G, Right Hand): Precisely gauges the targeted thread profile to ensure proper mating with components designed for M33 x 2 right-hand threads, improving fit and function.
• Durable hardened steel construction: With hardened steel, the gauge resists wear in busy workshops, maintains accuracy across many inspections, and stands up to daily use.

With its robust construction and clear Go/No-Go indicators, this gauge helps you speed up quality checks, reduce guesswork, and achieve consistent thread fits across production runs. By catching out-of-tolerance holes early, you can minimize rework, protect mating components, and maintain reliable performance in assemblies requiring metric fine threads.
