The JBO Thread Plug Gauge (GO) – Metric Fine – Right Hand – 6H – M125 x 1.5 is a precision go gauge designed to verify internal threads in metric fine-hole sizes. Ideal for engineers, machinists, quality inspectors, and maintenance teams, it helps confirm that threaded holes meet exact standards with fast, reliable go/no-go checks.

Crafted from hardened steel, this gauge delivers exceptional durability and wear resistance to stand up to busy workshop environments. The knurled, easy-grip body ensures secure handling and consistent alignment during insertion, making every inspection straightforward and repeatable.

• Hardened steel construction for long life: Built to endure frequent insertions and withdrawals while preserving dimensional accuracy, reducing replacement and downtime.
• Precise metric fine sizing for M125 x 1.5, right-hand, 6H: Specifically calibrated to the M125 x 1.5 thread form, providing reliable go checks that reflect true hole condition and prevent under- or over-threading.
• Ergonomic, easy-to-handle design: Knurled exterior and robust end-fitting enable quick, confident handling and fast verification—even when wearing gloves or working at pace.

Use this gauge to streamline quality control, accelerate assemblies, and achieve consistent results across production runs. Its dependable performance supports accurate hole verification, reduces rework, and helps you maintain tight tolerances with every part you inspect.
