The JBO Thread Plug Gauge is a precision tool built for metric fine threads, ideal for quality control in machining and assembly. Designed for right-handed threads with an M1 x 0.2 pitch and a 5H tolerance, this Go/No-Go gauge delivers quick, reliable checks to verify threaded holes meet exact specifications.

• Go/No-Go quick verification: Quickly determine if the hole matches the M1 x 0.2 metric fine-thread spec, accelerating part approval and reducing inspection time.
• Hardened steel construction: Built to resist wear and maintain accuracy in busy workshops, delivering long service life with minimal maintenance.
• Right-hand metric fine-thread design: Specifically configured for common small-thread applications, ensuring consistent, reliable checks across parts.

Using this gauge reduces guesswork in hole threading, speeds up assembly, and delivers consistent, repeatable results across batches. It supports lean QA processes by enabling quick pass/fail decisions, minimizing downtime and rework while extending tool life.
