The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. This Right Hand, 6G gauge is sized M32 x 1 and is ideal for checking threaded holes in machined parts and assemblies to ensure a perfect fit.

With its Go/No-Go design, you can quickly determine if a hole meets tolerance and stop when it’s outside. Built to endure the demands of busy workshops, the gauge uses hardened steel for long life and reliable performance even with frequent use.

• Go/No-Go Quick-Check: Streamlines hole inspection by clearly indicating pass/fail with GO and NO-GO ends, saving time and avoiding guesswork in quality checks.
• M32 x 1 Metric Fine-Thread Compatibility: Specifically designed for metric fine threads, ensuring accurate checks for components and assemblies using this precise pitch.
• Rugged, Color-Coded and Easy to Use: Hardened steel construction resists wear; knurled body and color-coded ends help you orient and use the gauge quickly in busy shop environments.

This plug gauge helps you speed up setup, improve measurement consistency, and protect downstream assembly quality. By providing a clear go/no-go decision on hole threads, it reduces rework, minimizes downtime, and supports repeatable results across multiple operators and machines.
