JBO Thread Plug Gauge is a precision instrument designed for metric fine threads. Specifically sized for M13 x 1 with right-hand orientation and 6G class, it enables quick Go/No-Go hole inspection to verify fit and tolerances. It's ideal for machinists, quality control teams, and assembly technicians who need reliable, fast checks.

Durable hardened steel construction ensures long-lasting performance and resistance to wear in busy workshops.

• Fast Go/No-Go verification: Quickly confirm both minimum and maximum thread conditions in metric holes, reducing inspection time and helping ensure components assemble correctly.
• Durable hardened steel construction: Built to withstand daily shop use, resisting wear and maintaining precision over many cycles.
• Metric fine-thread accuracy for M13 x 1 (Right Hand, 6G): Specifically sized and oriented for common metric holes, delivering consistent, reliable test results across setups.

Using this gauge streamlines quality checks, minimizes guesswork, and helps maintain consistent thread quality across parts and operators. The robust construction means fewer replacements, while the Go/No-Go feedback provides clear pass/fail signals for efficient setup, reducing downtime and boosting overall production reliability.
