The JBO Thread Plug Gauge (GO) – Metric Fine, Right Hand, 6H, M48 x 3 is a precision inspection tool designed to confirm the integrity of internal threads in a range of components. Ideal for machinists, quality control professionals, and maintenance technicians, it provides quick, reliable go/no-go checks to verify that threaded holes meet the required size and tolerance.

Crafted from hardened steel, this GO gauge offers durable performance in busy workshops. The metric fine thread specification (M48 x 3) and 6H tolerance ensure consistent results across production runs, while the right-hand design and knurled grip make handling straightforward even in tight spaces.

• Precise Go gauge for metric fine threads: Quickly verify that a threaded hole matches the M48 x 3, 6H specification with clear pass/fail results, helping you speed up quality checks and reduce rework.
• Hardened steel construction: Designed for long life and wear resistance in demanding shop environments, ensuring accurate measurements over many cycles.
• Ergonomic, knurled body for easy handling: The textured surface and right-hand orientation provide secure grip and fast placement in holes, improving inspection speed and accuracy.

Using this gauge, you can streamline QC workflows, catch misthreaded components early, and ensure reliable assembly in production lines. Its durable build and precise dimensions support consistent results across parts, helping you maintain quality, reduce downtime, and protect your downstream processes.
