The JBO Thread Plug Gauge GO is a precision inspection tool designed to verify internal threads in holes and components. Sized for metric fine threads M72 x 1.5 with a left-hand orientation, it enables quick go/no-go checks to ensure threaded holes meet exact specifications and standards.

Designed for reliability in demanding environments, the gauge is crafted from hardened steel for long-lasting wear. Its knurled body provides a secure grip and easy alignment, making insertions smooth and results consistent across QC checks and precision engineering tasks.

• Exact metric fine thread match (M72 x 1.5) with 6H tolerance: Provides precise go/no-go verification for holes that must meet tight specifications, reducing guesswork and rework.
• Left-hand thread design for LH hole checks: Optimized for inspecting left-handed threads, ensuring accurate readings and consistent results in LH applications.
• Hardened steel construction with knurled grip: Built for durability in busy workshops and easy handling, delivering reliable alignment for repeated use.

Using the JBO Thread Plug Gauge GO enables fast, reliable threaded-hole verification, minimizes downtime, and supports consistent quality across production runs. By validating holes to the M72 x 1.5 standard with 6H tolerance, it helps prevent misfits, streamlines inspections, and maintains high-precision results from first part to last.
