The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. It’s ideal for engineers, machinists, inspectors, and technicians who need quick, confident verification of threaded holes.

Specifically configured for right-hand metric fine threads (M35 x 1) with a 6G tolerance, this gauge delivers accurate go/no-go checks that speed setup and prevent misfits in assemblies.

• Go/No-Go quick-check design: Quickly verify hole acceptance with clear go and no-go segments, reducing inspection time and ensuring consistent fits with mating components.
• Durable hardened steel construction: Withstanding repeated use and wear, it delivers long service life in busy workshops and production lines.
• Metric fine-thread compatibility: M35 x 1, right-hand, 6G: Precisely calibrated for common metric fine threads, ensuring accurate size checks and reliable compatibility with standard fasteners.

This plug gauge helps you streamline quality control, minimize rework, and maintain tight tolerances across assemblies. By providing fast, repeatable checks, it supports faster setup, fewer production delays, and more consistent results in every project.
