JBO Thread Plug Gauge (GO) - Metric Fine - Left Hand - 6H - M56 x 2 is a precision inspection tool designed to verify threaded holes meet exact size and tolerance. This GO gauge helps machinists, quality inspectors, engineers, and workshop technicians confirm that holes are within spec without guesswork.

Made for durability in demanding environments, the plug gauge uses hardened steel for long wear resistance. The simple, clear design makes it easy to identify a properly threaded hole during quality control checks, supporting reliable, repeatable results across production runs.

• Precise GO gauge for metric fine threads (M56 x 2, 6H): Quickly verify that threaded holes match the exact size and tolerance, delivering clear go/no-go decisions in inspections.
• Hardened steel construction: Built to withstand daily use, resist wear, and maintain accuracy over many cycles.
• Left-hand orientation: Specifically designed for left-handed thread configurations, enabling fast checks and consistent results in teams that work with reverse-thread components.

Using the JBO GO thread plug gauge helps streamline quality control, reduce inspection time, and ensure every part that passes your line truly meets the threaded-hole standard. Its durable build and straightforward use support reliable performance across demanding applications, from initial production runs to final assembly.
