The JBO Thread Plug Gauge (GO) - Metric Fine - Left Hand - 6H - M82 x 1.5 is a precision go gauge used to verify the accuracy of internal threads in tapped holes. Ideal for machinists, quality inspectors, and manufacturing teams, it delivers fast, reliable checks to confirm holes meet exact specifications.

Crafted from hardened steel, this GO plug gauge resists wear and maintains calibration through heavy daily use. The metric fine size M82 x 1.5, paired with a 6H tolerance, is built for durability and repeatable results when validating thread quality.

• Hardened steel construction: Built to withstand daily use in demanding environments, delivering long service life and stable calibration.
• Accurate metric fine size M82 x 1.5 (Left-Hand) GO gauge: Precisely machined to enable quick, repeatable go checks for left-hand internal threads.
• Clear, user-friendly design for fast checks: Knurled body and straightforward go/no-go verification speed up quality control with minimal setup.

By providing a quick, reliable go-check, this gauge speeds threaded-hole inspections, minimizes guesswork, and supports consistent results across batches. Its rugged build reduces downtime and replacement costs, helping you maintain tight tolerances and reliable performance in production.
