The JBO Thread Plug Gauge is a precision Go/No-Go plug gauge built for metric fine threads. Sized for M19 x 1 right-hand threads with a 6H tolerance, it helps machinists, quality inspectors, and maintenance teams quickly verify threaded holes meet exact specifications and fit mating components with confidence.

Crafted from hardened steel, this gauge delivers durable, wear-resistant performance in busy workshop environments. The robust construction helps maintain consistent measurements through repeated checks, reducing downtime and rework.

• Go/No-Go Efficiency: Quickly verify threaded holes with a clear pass/fail indication, reducing inspection time and minimizing misfits in assembly.
• Durable Hardened-Steel Construction: Built to withstand daily workshop use, resisting wear and maintaining accurate measurements over thousands of checks.
• Metric Fine Thread Precision (M19 x 1, Right-Hand, 6H): Specifically matched to fine-pitched metric threads, ensuring reliable mating with components that require precise tolerance control.

Using this gauge, you’ll speed up inspections, reduce downtime, and ensure threaded holes consistently accept the correct mating parts. The hardened-steel construction stands up to busy shop environments, keeping accuracy intact after repeated use. With clear Go/No-Go results, you can confidently move from inspection to assembly, knowing your threads meet the required M19 x 1, 6H right-hand specification.
