The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. Specifically sized for M22 x 1 right-hand threads with a 6H tolerance, it enables quick, reliable checks of threaded holes to ensure smooth mating with fasteners and components.

Manufactured from hardened steel, this gauge is built to endure daily use in busy workshops and production environments, providing consistent performance over time.

• Go/No-Go quick checks for fast tolerance verification: Use the two-ended design to determine whether a threaded hole falls within spec in seconds—Go confirms acceptable threading, No-Go flags out-of-tolerance conditions, reducing guesswork and inspection time.
• Rugged hardened steel construction: Designed for durability and long tool life, resisting wear from repeated insertions and handling in demanding shop settings.
• Specifically sized for M22 x 1, right-hand metric fine threads (6H): Ensures accurate, repeatable fits for common metric assemblies, helping you achieve reliable assembly and consistent quality across parts.

By incorporating the JBO Thread Plug Gauge into your QC workflow, you gain fast, confident thread Verification, minimize rework, and maintain steady production throughput. It supports inbound and in-process inspection, helping teams prevent misfits and ensure precise mating with fasteners and components every time.
