The JBO Thread Plug Gauge (NoGo) - Metric Fine is a precision measuring tool designed to verify metric fine thread holes. Configured for left-hand threads, this gauge targets the M70 x 1.5 size within the 6H class, making it ideal for quality control, inspection, and maintenance across manufacturing and engineering workflows.

Machined from hardened steel and finished with a textured knurl, the gauge offers long-lasting durability and a secure grip in busy workshop environments. Its robust construction resists wear and maintains accurate dimensions through repeated use, even in demanding conditions.

• Metric Fine compatibility (M70 x 1.5, 6H): Delivers repeatable NoGo checks for this exact size and thread class, helping you identify out-of-tolerance holes quickly and reliably.
• Left-Hand configuration: Designed for applications using left-hand threads, ensuring correct inspection without confusion or guesswork.
• NoGo verification: Engineered to prevent oversized holes, yielding fast, unambiguous pass/fail results to speed up inspections and reduce rework.

Used in quality control to confirm threaded holes meet specification, the JBO Metric Fine NoGo Thread Plug Gauge helps streamline workflows, cut inspection time, and support consistent, repeatable results across parts and batches.
