Description

The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads, enabling quick Go/No-Go checks of threaded holes to confirm proper fit.

This left-handed version targets M40 x 1 threads with a 6H tolerance, helping you ensure correct engagement with left-handed components. Built from hardened steel for long-lasting wear resistance, it stands up to daily use in demanding workshop environments.

  • Go/No-Go quick validation: Instantly confirms whether the hole thread falls inside spec with a simple pass/fail check, speeding up inspections and reducing guesswork.
  • Left-Hand Thread Compatibility (M40 x 1, 6H): Precisely tuned for left-handed threads, ensuring accurate validation and reliable mating with the correct components.
  • Hardened steel construction with knurled grip: Built for durability and easy handling, providing long service life in busy shop environments and repeatable measurements.

With the JBO Thread Plug Gauge, quality control becomes faster and more reliable. You can trim setup time, minimize rework, and ensure consistent, accurate thread engagement across parts and assemblies. The rugged construction and precise tolerance support repeatable results on busy production lines, making it a trusted tool for engineers, machinists, inspectors, and assembly teams alike.
