The JBO Thread Plug Gauge is a precision tool designed for metric fine threads. It's ideal for machinists, quality inspectors, and assembly teams who need fast, reliable confirmation that threaded holes will accept mating parts without surprises.

Designed as a Go/No-Go plug gauge for right-hand M14 x 1.25 threads with a 6H tolerance, it delivers quick pass/fail checks while resisting wear through hardened steel construction. This combination provides durable, repeatable checks in busy workshops.

• Go/No-Go quick verification: The Go/No-Go design provides clear pass/fail results for threaded holes, speeding setup and reducing guesswork during assembly.
• Hardened steel construction: Hardened steel resists wear and maintains accuracy across many inspections, even in demanding environments.
• Metric fine thread compatibility: M14 x 1.25, 6H, right-hand: Precisely sized for metric fine holes, delivering repeatable checks and confidence in mating parts.

With the JBO Thread Plug Gauge, you gain faster, more reliable thread inspection that supports consistent assembly quality. It helps you catch undersized or oversized threads before they become costly downtime, reduce rework, and streamline QC workflows across engineering, manufacturing, and maintenance tasks.
