The JBO Thread Plug Gauge is a precision tool for metric fine threads, designed to quickly verify hole acceptance without guesswork. With a rugged, knurled body for a secure grip and a dual-ended Go/No-Go design for right-hand M16 x 1 holes (6H), it delivers fast, reliable checks in any workshop or QA station.

• Go/No-Go quick verification: Instantly confirm whether a threaded hole is within tolerance, speeding up setup and reducing downtime by eliminating guesswork.
• Hardened steel durability: Built to endure daily use, resisting wear and corrosion to maintain accuracy and extend gauge life in busy environments.
• Right‑hand M16 x 1 6H precision design: Specifically tuned for metric fine threads, ensuring repeatable, consistent checks across parts and production runs.

By delivering fast, reliable Go/No-Go verification for M16 x 1 threads, the gauge speeds up setup, reduces downtime, and helps your team make confident pass/fail decisions. Its hardened steel body stands up to everyday use, preserving accuracy and minimizing calibration drift. Whether in a machining cell, QA lab, or field workshop, this plug gauge supports consistent hole quality and repeatable results across your production workflow.
