The JBO Thread Plug Gauge (GO) is a precision inspection tool designed to verify threaded holes that use metric fine threads. It’s specifically sized for M50 x 2 with a right-hand orientation and 6H tolerance, making it ideal for ensuring holes meet exact thread standards. Crafted from hardened steel, this GO gauge delivers durable, repeatable performance in demanding shop environments, with a knurled body that provides a secure grip for clean, confident insertions.

• GO gauge for metric fine threads (M50 x 2 RH, 6H): Precisely matches the target hole so you can quickly confirm acceptance, speeding up quality checks and reducing guesswork.
• Hardened steel construction: Built to withstand frequent use and resist wear, maintaining accuracy and extending service life in busy work settings.
• Ergonomic, user-friendly design: Knurled grip and straightforward geometry enable easy handling, insertion, and identification of properly threaded holes, supporting consistent results.

In daily QC and precision engineering workflows, this gauge helps you verify hole compliance efficiently, reduce inspection time, and preserve consistent performance across batches and maintenance tasks.
