The JBO Thread Plug Gauge (GO) – Metric Fine, Right Hand, 6H, M45 x 1 is a precision inspection tool designed to quickly verify the accuracy of metric fine threaded holes. Its GO gauge format is ideal for quality checks, helping engineers, machinists, and inspectors confirm that a hole accepts the correct thread without guesswork.

Made for demanding environments, this gauge uses hardened steel and a carefully controlled finish to deliver consistent results across production runs and field service. The right-hand orientation and standard 6H tolerance support reliable, repeatable measurements in everyday workshop tasks.

• Metric Fine GO for M45 x 1 threads: Accurately verifies that a threaded hole accepts the M45 x 1 metric fine thread, enabling quick pass/fail decisions during inspection and assembly.
• Hardened steel construction for durability: Delivers long-lasting wear resistance, reducing downtime and replacement costs in busy shops and production lines.
• Right-hand orientation for standard checks: Aligns with common internal thread direction, making setup intuitive and minimizing misreads during routine QC tasks.

With the JBO Thread Plug Gauge, you can streamline quality control, shorten inspection times, and improve confidence in every assembly. Its durable build stands up to daily use in metalworking, aerospace, automotive, and general manufacturing environments, while its precise sizing ensures consistent results across parts and batches. This gauge helps teams catch issues early, reduce rework, and maintain tight tolerances with minimal training or setup.
