The JBO Thread Plug Gauge (GO) – Metric Fine – Right Hand – 6H – M56 x 1.5 is a precision inspection tool designed to quickly verify threaded holes meet exact standards. Ideal for manufacturing, maintenance, and quality-control environments, this GO gauge helps confirm that a hole accepts the plug as intended, ensuring components conform to the required M56 x 1.5 fine-thread specification and 6H tolerance.

• Precise GO gauge for fast hole verification: enables quick go/no-go checks to confirm threaded holes meet the M56 x 1.5 metric fine specification with 6H tolerance, speeding up quality assessments.
• Hardened steel construction for durability: built to resist wear in busy workshops, delivering long service life and reliable performance over many inspections.
• User-friendly identification of properly threaded holes: clear GO designation and ergonomic design help inspectors insert and remove the gauge smoothly, even when wearing gloves, reducing errors in quality control.

By incorporating this gauge into your inspection routine, you can streamline threaded-hole verification, reduce rework, and maintain consistent part quality across production and maintenance workflows. Its robust build and straightforward operation provide confidence in every measurement, helping you meet tighter tolerances with repeatable results.
