The JBO Thread Plug Gauge is a precision tool designed to verify metric fine-thread holes with confidence. This Right Hand, Go/No-Go gauge is specifically matched to M14 x 1 threads within the 6H tolerance class, enabling fast, accurate checks during manufacturing, quality control, and assembly.

Constructed from hardened steel, the gauge resists wear in busy workshop environments. Its knurled grip and compact, easy-to-handle form make inspections quick and repeatable, even in tight spaces.

• Go/No-Go design for fast checks: Quickly verify that internal threads meet the exact 6H spec—Go confirms the hole accepts the thread within tolerance, while No-Go ensures it does not exceed it, reducing guesswork and rework.
• Hardened steel for durability: Built to withstand daily use, resisting wear and maintaining accuracy over many inspections for long-lasting reliability.
• Precise M14 x 1 right-hand, 6H timing: Specifically tuned for metric fine threads, delivering consistent results and confidence that components will screw together correctly on every production run.

With the JBO Thread Plug Gauge, you can streamline thread validation, minimize downtime, and achieve reliable, repeatable results across parts and assemblies that require M14 x 1 right-hand threads within the 6H tolerance. A practical, dependable addition to any shop or quality control station.
