The JBO Thread Plug Gauge is a precision Go/No-Go gauge designed for metric fine threads. Specifically sized for M22 x 1.5 with a 6H tolerance, this left-hand configuration helps quality teams quickly verify threaded holes during assembly or maintenance, ensuring components fit together with confidence.

Its rugged construction uses hardened steel to resist wear in busy workshops, delivering reliable performance over many checks. The ergonomic, knurled body provides a secure grip for precise placement during inspections, making it easy to use in cluttered workspaces.

• Go/No-Go Quick-Check Design: Instantly verify threaded holes for proper fit—one simple pass confirms Go, and a No-Go check flags undersized or oversized holes, speeding inspections without guesswork.
• Hardened Steel Construction: Built to endure busy workshop conditions, resisting wear and corrosion for long service life and dependable results.
• Precise M22 x 1.5, 6H Sizing with Left-Hand Configuration: Specifically matched metric fine-thread dimensions in a left-hand setup to ensure accurate testing of compatible holes and consistent results across parts.

This gauge helps you streamline quality control, reduce downtime, and boost confidence in every threaded assembly. Its robust design and practical Go/No-Go functionality support faster, repeatable inspections, whether you’re in a manufacturing line, repair shop, or field service environment.
