The JBO Thread Plug Gauge (GO) is a precision tool designed to quickly and reliably verify metric fine-thread holes. Suitable for production lines, workshops, and quality-control labs, it helps ensure threaded components meet exact specifications with a simple go/no-go check. This GO gauge targets the M65 x 3 size with 6H tolerance, providing a straightforward pass/fail indication for accurate assemblies.

Crafted from hardened steel, the gauge delivers durable performance in demanding environments. Its robust construction resists wear from repeated use, helping maintain measurement integrity over time. The right-hand design and knurled grip make insertion smooth and consistent, supporting efficient inspection workflows without guesswork.

• Precise GO gauge for metric fine threads: Quickly confirms holes are threaded to M65 x 3 with 6H tolerance, speeding up quality checks and reducing guesswork.
• Durable hardened steel construction: Built to withstand daily use in busy shops, delivering lasting accuracy and resist wear that could affect readings.
• User-friendly, right-hand design: Easy to deploy in standard QC routines with a comfortable grip, ensuring reliable identifications of properly threaded holes.

Used correctly, this gauge helps streamline inspection, minimize rework, and improve the consistency of threaded assemblies across manufacturing, engineering, and maintenance environments.
