The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. It’s ideal for engineers, machinists, quality inspectors, buyers, and workshop enthusiasts who need reliable hole-thread verification. Use it to quickly confirm that threaded holes match exact specifications so components fit together with confidence.

This right-hand gauge tests metric fine threads with a Go/No-Go design, delivering fast, unambiguous results. Built with hardened steel, it resists wear through repeated use, maintaining accuracy and extending tool life in busy shops.

• Go/No-Go quick verification for metric fine threads: Quickly confirm hole tolerance using separate go and no-go checks, speeding setup and reducing guesswork.
• Hardened steel construction for lasting reliability: Resists wear from repeated use, keeping measurements accurate and the tool durable in demanding environments.
• Precise fit for M11 x 0.5 right-hand threads (6H): Engineered for accurate testing of metric fine holes, ensuring consistent results across parts and processes.

With the JBO Thread Plug Gauge, you streamline quality checks, shorten setup times, and reduce the risk of mismatched components. Its robust construction and precise tolerances help your team deliver consistent, high-quality assemblies—whether in high-volume production or hands-on workshops.
