The JBO Thread Plug Gauge is a precision tool for metric fine threads, designed to verify hole threads quickly and accurately. It's ideal for machinists, quality inspectors, and assembly teams working with M14 x 1.5 right-hand threads, helping you confirm a correct fit before parts move to the next step.

With a Go/No-Go design and a robust construction, this gauge speeds up inspection while delivering reliable pass/fail results. Built for demanding shop environments, its hardened steel body resists wear, maintaining accuracy through countless checks.

• Go/No-Go quick inspection: Quickly verify whether the threaded hole accepts the M14 x 1.5 right-hand thread within tolerance, reducing guesswork and rework.
• Metric fine-thread compatibility (M14 x 1.5, right-hand, 6H): Specifically matched to common metric fine-thread holes, ensuring consistent mating performance.
• Hardened steel construction: Built to endure daily use, resist wear, and maintain accuracy across thousands of checks.

This plug gauge helps streamline quality control by delivering fast and repeatable checks that minimize downtime and wasted parts. Its durable, reliable design ensures long service life in busy workshops, while the precise fit provides confidence that each hole will accept and mate with the corresponding M14 x 1.5 thread parts. By standardizing acceptance criteria, teams can speed setups, reduce rework, and improve overall threading quality across assemblies.
