The JBO Thread Plug Gauge is a precision inspection tool designed specifically for metric fine threads. It helps machinists, quality control technicians, and assembly staff quickly verify threaded holes to ensure parts fit together smoothly and consistently.

This Right Hand gauge features a Go/No-Go design and is specified for M19 x 0.75 with a 6H tolerance, delivering fast, reliable checks that support efficient production and repeatable results.

• Go/No-Go Quick Verification: Enables instant pass/fail checks for the M19 x 0.75 6H internal threads, reducing inspection time and the chance of misfits.
• Rugged Hardened Steel Build: Built to withstand daily use in busy workshops, resisting wear and preserving accuracy over many cycles of insertion and removal.
• Metric Fine-Thread Compatibility: Specifically tuned for metric fine threads to deliver consistent, reproducible results across parts and assemblies.

Use this gauge to streamline quality checks, minimize rework, and ensure reliable, repeatable threading results across production runs.
