The JBO Thread Plug Gauge (GO) — Metric Fine — Right Hand — 6H — M78 x 2 is a precision inspection tool designed to quickly verify threaded holes. It helps quality teams, machinists, and inspectors confirm that holes meet the exact metric fine, right-hand standard you specify, delivering consistent go/no-go results during assembly and inspection processes.

Engineered for durability and reliable performance, this GO plug gauge is crafted from hardened steel to resist wear in busy workshop environments. Its robust construction maintains accurate measurements over many uses, reducing the need for rechecks and increasing confidence in every threaded assembly.

• Go/No-Go quick verification: Enables rapid confirmation that a hole threads to the M78 x 2 metric fine right-hand standard, speeding up QC and minimizing rework.
• Durable hardened steel construction: Withstands daily industrial use, delivering lasting accuracy and extended tool life in demanding environments.
• Metric fine, right-hand compatibility: Precisely matched to 6H tolerance and standard metric threads, ensuring consistent measurements and easier training for operators.

Used across manufacturing, maintenance, and quality control, this gauge helps you streamline inspections, improve workflow consistency, and achieve reliable threaded-hole results with every check.
