The JBO Thread Plug Gauge (GO) – Metric Fine, Left Hand, 6H, M62 x 1.5 is a precision inspection tool designed to quickly verify internal threads in machined parts. It’s ideal for manufacturing engineers, quality inspectors, machinists, and maintenance technicians who need reliable go/no-go checks to confirm hole suitability and ensure proper assembly fit.

Crafted from hardened steel for outstanding durability, this GO gauge resists wear in busy shop environments while delivering consistent readings over many inspections. The left-hand configuration and metric fine size are tailored for right-sized, fast checks on components that use M62 x 1.5 threads, helping you identify properly threaded holes with confidence.

• Precise metric fine threading (M62 x 1.5, 6H GO): Delivers reliable pass/fail indications for threaded holes, speeding up inspection and reducing rework.
• Durable hardened steel construction: Built to withstand daily use in demanding environments while maintaining accuracy over time.
• Left-Hand design for easy checks: Specifically oriented for left-handed thread applications, simplifying setup and minimizing misreads during inspection.

Using the JBO Thread Plug Gauge (GO) helps you streamline quality control, shorten setup times, and achieve consistent results across parts and shifts. Its combination of precise Go measurement, robust build, and thoughtful orientation supports faster, more confident decisions in every inspection cycle.
